​Factor Combinations

• ​ Factors are numbers that you use to multiply to get the required number. In the equation, 3 x 2 = 6, the factors of 6 are 3 and 2.

  Composite Numbers - Some numbers have more than 2 factor combinations like 9. The combinations to multiply to get 9 are 1 x 9 and 3 x 3. Numbers that have more than just the factor combination 1 and itself are called composite numbers.

• Prime Numbers - 2 is a prime number because the only factor combination it has is 1 x 2. Numbers that have only one combination of factors - 1 and itself - are called prime numbers.

EG: 2,3,5,7,11,13........ARE SOME PRIME NUMBERS

​​COMPOSITE NUMBERS

A NUMBER WHICH HAS MORE THAN TWO FACTORS ARE COMPOSITE NUMBERS

EG: 4,6,8,9,10,12,14.........ARE COMPOSITE NUMBERS
