Therefore, GCD of numbers 721, 154, 883, 653 is 1

Given Input Data is 721, 154, 883, 653

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

Prime Factorization of 721 is 7 x 103

Prime Factorization of 154 is 2 x 7 x 11

Prime Factorization of 883 is 883

Prime Factorization of 653 is 653

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(721, 154) = 15862

GCD(721, 154) = ( 721 x 154 ) / 15862

GCD(721, 154) = 111034 / 15862

GCD(721, 154) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 883

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

LCM(7, 883) = 6181

GCD(7, 883) = ( 7 x 883 ) / 6181

GCD(7, 883) = 6181 / 6181

GCD(7, 883) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 653

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

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

GCD(1, 653) = 653 / 653

GCD(1, 653) = 1

GCD of 721, 154, 883, 653 is 1
