Answer:
12
Explanation:
If 113 divided by a number leaves a remainder of 5, then we need to find the prime factorization of 108.
If 135 divided by a number leaves a remainder of 3, then we need to find the prime factorization of 132.
If 160 divided by a number leaves a remainder of 4, then we need to find the prime factorization of 156.
108 = 2² × 3³
132 = 2² × 3 × 11
156 = 2² × 3 × 13
The GCF of 108, 132, and 156 is common factors with lower exponent.
GCF = 2² × 3 = 12
