What is the fastest way to find the highest common factor (HCF) between two numbers — and how can you be sure your answer is correct? The quickest method is to: Identify all the factors of the smaller number. Check these from largest to smallest to see which one divides evenly into the larger number. Once you find a factor that divides both numbers evenly, you’ve found the HCF. Let’s walk through this with an example. ...
What’s the fastest way to find the highest common factor (HCF) of two numbers — and how can you check your answer? The most efficient method is: Find all the factors of the smaller number. Starting from the largest factor, check which ones also divide the larger number exactly. As soon as one does — that’s your HCF. Let’s try this with 32 and 24. HCF of 32 and 24 Step-by-step: ...
What’s the fastest way to find the highest common factor (HCF) of two numbers — and how can you check your answer? The most efficient method is: Find all the factors of the smaller number. Starting from the largest factor, check which ones also divide the larger number exactly. As soon as one does — that’s your HCF. Let’s try this with 18 and 24. HCF of 18 and 24 Step-by-step: ...
What’s the fastest way to find the highest common factor (HCF) of two numbers — and how can you check your answer? The most efficient method is: Find all the factors of the smaller number. Check, from largest to smallest, which of these also divides the larger number exactly. As soon as one does — that’s your HCF. Let’s walk through an example. HCF of 16 and 40 Step-by-step: Smaller number is 16. ...
How can you quickly find the factors of a number? Factors are the numbers that divide into another number without leaving a remainder and can never be bigger than the original number. To find factors quickly start with the number 1 and ask yourself the question: can 1 be divided into thr original number without leaving a remainder. As 1 will go into every integer obviously the answer will be yes every time. ...
How can you quickly find the factors of a number? Factors are numbers that divide into another number without leaving a remainder. A factor is always less than or equal to the original number. To find factors quickly: Start with 1 and your original number. Begin testing numbers from 2 upwards: Ask: Does this number divide into the original number with no remainder? If yes, add both the divisor and its quotient to your list. Stop once your test number exceeds the square root of the original number. If the only factors are 1 and the number itself, the number is prime. If there are more than two, the number is composite. ...
How can you quickly find the factors of a number? Factors are the numbers that divide evenly into another number — with no remainder. A factor is always less than or equal to the original number. To find all factors quickly: Start with 1 and the original number — these are always factors. Test each number starting from 2: Ask: Does this number divide into the original without a remainder? If yes, add both the divisor and the quotient to your list. Stop when you pass the square root of the number. If you end with only 1 and the number itself, it’s prime. If you find more than two factors, it’s composite. ...
How can you quickly find the factors of a number? Factors are the numbers that divide evenly into another number — that is, with no remainder. Factors are never greater than the number itself. To find all the factors of a number: Start at 1 — since 1 is a factor of every number. Then try 2, 3, 4, and so on. Stop once you reach or pass the square root of the number. Let’s go through this process step-by-step for the number 29. ...
How do you find the lowest common multiple between two numbers quickly — and how can you check that your answer is correct? The lowest common multiple (LCM) of two numbers is the smallest number that both divide into evenly. For the numbers 8 and 12, the LCM is 24. Let’s look at the most efficient way to find it. Step-by-Step Method To Find LCM The most effective method is to use multiples of the larger number and test whether the smaller number divides into them evenly. ...
How do you find the lowest common multiple between two numbers quickly — and how can you check your answer? The lowest common multiple (LCM) of two numbers is the smallest number that both divide into with no remainder. For the numbers 8 and 10, the LCM is 40. Let’s explore the most efficient way to find it. Step-by-Step Method To Find LCM The most effective strategy is to use multiples of the larger number and check if the smaller number divides into any of them. ...
