Question

Write the sum of the numbers as a product of their GCF and another sum using the distributive property.42 + 36

Answer 1

GCF = Greatest Common Factor

Therefore,

prime factor of 42

`42\text{ = }2*3*7`

prime factor of 36

`36=2*2*3*3`
`As\text{ 2}*3=6,\text{ GCF=6}`

Therefore,

`42+36=6*7+6*6=6*(7+6)`
