Step by Step

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 1 and the original number. Begin testing integers from 2 upward. If a number divides evenly, add both the divisor and its quotient to your list. Stop once your checking number exceeds the square root of the original number. If you only find two factors (1 and itself), it’s a prime number. If you find more than two, it’s a composite number. ...

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: Can this number divide into the original number without leaving a remainder? Since 1 divides into every number, you can begin checking from 2 — knowing your factor list already includes 1 and the original number. ...

How can you quickly find the factors of a number? Factors are numbers that divide into another number without leaving a remainder. They can never be greater than the number itself. To find factors quickly: Start with 1 and the number itself (since 1 always divides evenly). Begin testing integers from 2 upwards. If a number divides evenly, add both the divisor and its quotient to your list. Stop once the checking number exceeds the square root of the original number. If the number only has two factors (1 and itself), it’s a prime number. If it has more than two, it’s a composite number. ...

What’s the fastest way to find the highest common factor (HCF) of two numbers — and how can you check your answer? The quickest method is: Find all the factors of the smaller number. From the largest factor down, test whether it also divides the larger number exactly. Once you find such a factor, stop. That’s your HCF. HCF of 32 and 48 Step-by-step process: Smaller number is 32 Factors of 32: $[1, 2, 4, 8, 16, 32]$ ...

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 26 and 36. HCF of 26 and 36 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 quickest method is to: Find all the factors of the smaller number. Check, starting from the largest, which one divides the larger number exactly. Once you find the biggest number that divides both, that’s your HCF. Let’s look at an example. HCF of 8 and 12 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 quickest method is: Find all the factors of the smaller number. Check, from largest down, which of those divide the larger number exactly. Once you find the biggest number that divides both, that’s your HCF. Let’s walk through an example. HCF of 12 and 18 Step-by-step: Smaller number is 12. ...

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, follow this process: Start with 1 and your original number — these are always factors. 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 your final list contains only 1 and the original number, then the number is prime. ...

How can you quickly find the factors of a number? Factors are numbers that divide evenly into another number — with no remainder. A factor can never be greater than the number itself. To find factors quickly: Start with 1 and the number itself — these are always factors. Begin checking each number from 2 upwards: Ask: Does this number divide into the original without remainder? If yes, add both the divisor and the quotient. Stop when your checking number exceeds the square root of the original number. If the result has only two factors, it’s prime. If it has more than two, it’s composite. ...
