How do you do divide 1000 by 3? How can you do division on these two numbers and then check you’ve got the right answer? Division helps to answer how many times a number fits into another number and if there is anything remaining. Therefore, division involves two numbers to start: the divisor and the dividend. When you ask a division question like: what is 1000 divided by 3 the first number is the dividend and the second number is the divisor. ...
How do you do divide 180 by 2? How can you do division on these two numbers and then check you’ve got the right answer? Division helps to answer how many times a number fits into another number and if there is anything remaining. Therefore, division involves two numbers to start: the divisor and the dividend. When you ask a division question like: what is 180 divided by 2 the first number is the dividend and the second number is the divisor. ...
How do you do divide 116 by 2? How can you do division on these two numbers and then check you’ve got the right answer? Division helps to answer how many times a number fits into another number and if there is anything remaining. Therefore, division involves two numbers to start: the divisor and the dividend. When you ask a division question like: what is 116 divided by 2 the first number is the dividend and the second number is the divisor. ...
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 the original number without leaving a remainder. As 1 will go into every integer obviously the answer will be yes every time. ...
What Is a Prime Number? A prime number is a number that has exactly two factors: (1) Itself If a number has more than two factors, it is called a composite number. Step-by-Step: Is 57 Prime? To test whether 57 is a prime number, try dividing it by all prime numbers up to ( \sqrt{57} \approx 7.5 ). Step 1: Try 2 [ 57 \div 2 = 28.5 \quad \text{❌ Not divisible} ] ...
What Is a Prime Number? A prime number is a whole number greater than 1 that has exactly two factors: 1 itself If a number has more than two factors, it is not a prime number—it is called a composite number. Step-by-Step Check: Is 57 Prime? Let’s determine whether 57 is a prime number. Step 1: Try dividing by 2 $$ 57 \div 2 = 28.5 \quad \text{❌ Not divisible} $$ ...
What Is a Prime Number? A prime number is a number that has exactly two factors: (1) itself If a number has more than two factors, it is called a composite number. Step-by-Step: Is 53 Prime? Let’s determine whether (53) is a prime number by testing divisibility from the smallest primes upward. Try dividing 53 by small primes: (53 \div 2 = 26.5) → ✖️ Not divisible (53 \div 3 = 17.67) → ✖️ Not divisible (53 \div 4 = 13.25) → ✖️ Not divisible (53 \div 5 = 10.6) → ✖️ Not divisible (53 \div 6 = 8.83) → ✖️ Not divisible (53 \div 7 = 7.57) → ✖️ Not divisible Now that we’ve reached beyond (\sqrt{53} \approx 7.28), we can stop checking. ...

What is the fastest way to finding the highest common factor (HCF) between two numbers, and how can you check your answer? The quickest way to find the highest common factor between two numbers is to start by identifying all the factors of the smallest number first, then with this list, starting from the biggest factors, see if each number divides into the larger number without leaving a remainder. As you progress down through the list of factors (from the smaller number) when you find a number that divides into the larger number you can stop as you have found the highest common factor of both numbers. ...
