Answer:
GCF of the numbers is 3 and it can be written as 3(1+5)
Step-by-step explanation:
Given the expression 3+15
First we need to find their factors
3 = 3×1
15 = 3×5
Since 3 is common to both factors, hence the GCF is 3
Factorize
3+15
= (3×1)+(3×5)
Factoring 3 out
= 3(1+5)
Hence the GCF of the numbers is 3 and it can be written as 3(1+5)
