Given Input Data is 72, 56, 88, 56

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 56 is 2 x 2 x 2 x 7

Prime Factorization of 88 is 2 x 2 x 2 x 11

Prime Factorization of 56 is 2 x 2 x 2 x 7

Highest common occurrences in the given inputs are 2³

Multiplying them we get the GCD as 8

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(72, 56) = 504

GCD(72, 56) = ( 72 x 56 ) / 504

GCD(72, 56) = 4032 / 504

GCD(72, 56) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 88

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(8, 88) = 88

GCD(8, 88) = ( 8 x 88 ) / 88

GCD(8, 88) = 704 / 88

GCD(8, 88) = 8

Step3:

Here we consider the GCD from the above i.e. 8 as first number and the next as 56

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(8, 56) = 56

GCD(8, 56) = ( 8 x 56 ) / 56

GCD(8, 56) = 448 / 56

GCD(8, 56) = 8

GCD of 72, 56, 88, 56 is 8
