Therefore, GCD of numbers 72, 855, 893, 128 is 1

Given Input Data is 72, 855, 893, 128

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 855 is 3 x 3 x 5 x 19

Prime Factorization of 893 is 19 x 47

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

The above numbers do not have any common prime factor. So GCD is 1

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, 855) = 6840

GCD(72, 855) = ( 72 x 855 ) / 6840

GCD(72, 855) = 61560 / 6840

GCD(72, 855) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 893

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

LCM(9, 893) = 8037

GCD(9, 893) = ( 9 x 893 ) / 8037

GCD(9, 893) = 8037 / 8037

GCD(9, 893) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 128

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

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

GCD(1, 128) = 128 / 128

GCD(1, 128) = 1

GCD of 72, 855, 893, 128 is 1
