Test yourself…What are the factors and products?
1) 6 x 7 = 42
2) 63 ÷ 9 = 7
3) 8 x 5 = 40
Factors: 6 and 7Product: 42
Factors: 7 and 9Product: 63
Factors: 5 and 8Product: 40

One is special because . . .
One is not prime.(because it doesnot have exactly
two differentfactors).
One is not Composite.(because it doesnot have morethan 2 factors).
