What goes into 297?
Little Mathematical trick. If the digits in a number add up to 3 or a multiple of 3 then that number is divisible by 3. If the digits of a number add up to 9 or a multiple of 9 then that number is divisible by 9. 2 + 9 + 7 = 18 ........which is a multiple of both 3 and 9. Lets start with 3 297 ÷ 3 = 99 (9 + 9 = 18 so we can divide again by 3 and/or9) 99 ÷ 3 = 33 (3 + 3 = 6 so we can divide by 3) 33 ÷ 3 = 11 (11 is a prime number so no more factors. The prime factors of 297 are 33 and 11. The factors of 297 are : 297, 99, 33, 27, 11, 9, 3 and 1
