Question

1. find the
H. C.F. of the following
number
12,72
​

Answer 1

Step-by-step explanation:

Greatest Common Factor of 12 and 72

Greatest common factor (GCF) of 12 and 72 is 12.

GCF(12,72) = 12

We will now calculate the prime factors of 12 and 72, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 12 and 72.

Answer 2

Answer:

12 = 2 × 2×3

72 = 2×2×2×3×3

so hcf is 12
