Question

factors of 42 45 and 48​

Answer 1

step 1 Address the method, input parameters & values

Integers: 42, 45, 48

find gcf (42, 45 and 48) = ?

step 2 Find the prime factors of all integers of the group

42 = 2 x 3 x 7

45 = 3 x 3 x 5

48 = 2 x 2 x 2 x 2 x 3

step 3The common prime factor or the product of all common prime factors between all integers is the highest common factor of this group of integers (42, 45 & 48).

GCF(42, 45, 48) = 3
