Question

(a)Find the greatest common factor (GCF) of 45 and 54 .

(b) Use the GCF to factor 45 + 54


(a) GCF = 9
(b) 45 + 54 = 99 × ( __ + ____ )

Answer 1

Answer:he GCF of 54 and 45 is 9. To calculate the GCF of 54 and 45, we need to factor each number (factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54; factors of 45 = 1, 3, 5, 9, 15, 45) and choose the greatest factor that exactly divides both 54 and 45, i.e., 9.
