Factors And Multiples Gcse Maths Steps Examples Example 1: listing factors (odd number) list the factors of 15.15. state the pair 1 × n1 × n. as n = 15, n = 15, you have the first factor pair 1 × 15.1 × 15. 2 write the next smallest factor of nn and calculate its factor pair. as 1515 is an odd number, 15 ÷ 215 ÷ 2 is not an integer and so 22 is not a factor of 15.15. Factors and multiples; factors and multiples are easily mixed up. remember multiples are the multiplication table, whereas factors are the numbers that go into another number without a remainder. remember the number itself for factors and multiples; all numbers are a factor of themselves and a multiple of themselves. for example, think of the.
Factors And Multiples Gcse Maths Steps Examples Example 3: listing factors (square number) list the factors of 36.36. state the pair 1 × n.1 × n. show step. as n = 36, n = 36, we have the first factor pair 1 × 36.1 × 36. write the next smallest factor of nn and calculate its factor pair. show step. as 3636 is an even number, 22 is a factor of 36.36. Multiples of 2. multiples are really just extended times tables. the multiples of 2 are all the numbers in the 2 times table, such as 2, 4, 6, 8, 10 and so on. multiples of 2 always end with: 2, 4. The multiples of a number are the values in that number’s times table. for example, the multiples of 5 are 5, 10, 15, 20, 25 and so on. factor pairs are two integers which multiply together to. A. factor pair. close. factor pair two numbers that, when multiplied together, make a selected whole number. eg, 3 and 4 are multiplied together to make 12 so 3 and 4 are a factor pair of 12. a.

E list,916 1927 28 wri. down a factor of 12 write down a multiple of 7. s on the list.(total for question. 18 is 3 marks)19 gary is thinking of a number. he says. “my number is prime and it is a factor of 36”ther. are two possible numbers gar. write down these two numbers. (total for question 19 is 2 marks). 20 is not in the 3 times table, so 3 is not a factor. 4 × 5 = 20. we don't need to check any other numbers because we would only get repeats of the ones we already have. the factors of 20 are: 1, 2, 4, 5, 10 and 20. example 2: write down all the factors of 16. we will check in order again: 1 × 16 = 16. 2 × 8 = 16.
