 Divisibility Factoring If a number can be expressed as a product of two or more whole numbers, then the whole numbers are called factors of that number. 6 = 6 x 1 or 6 = 3 x 2 So, the factors of 6 are 1, 2, 3 and 6. A factor is any number that will divide into another number exactly (with no part left over) e.g. 8 can be divided by 2 (the factor in this example) 4 times. However, in total the number 8 has several factors: 1, 2, 4 and 8. Factors of 24: 1, 2, 3, 4, 6 ,8, 12, 24 Factors of 27: 1, 3, 9, 27 Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56 Factors of 61: 1, 61 Numbers that are greater than 1 and has only two positive factors; 1 and itself are called prime numbers Find three factors of 231, different to 231 or 1
