Question

use the gcf to factor the expression 40x + 24y - 56. type your answer...

Explanation:

Step1: Find GCF of 40,24,56

Factors of $40$: $1,2,4, 8,10,20,40$
Factors of $24$: $1,2,3,4,6, 8,12,24$
Factors of $56$: $1,2,4,7, 8,14,28,56$
GCF = $8$

Step2: Factor out GCF

$8\times5x + 8\times3y - 8\times7 = 8(5x +3y -7)$

Answer:

$8(5x + 3y -7)$
