Therefore, GCD of numbers 77, 182, 127, 858 is 1

Given Input Data is 77, 182, 127, 858

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

Prime Factorization of 77 is 7 x 11

Prime Factorization of 182 is 2 x 7 x 13

Prime Factorization of 127 is 127

Prime Factorization of 858 is 2 x 3 x 11 x 13

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(77, 182) = 2002

GCD(77, 182) = ( 77 x 182 ) / 2002

GCD(77, 182) = 14014 / 2002

GCD(77, 182) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 127

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

LCM(7, 127) = 889

GCD(7, 127) = ( 7 x 127 ) / 889

GCD(7, 127) = 889 / 889

GCD(7, 127) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 858

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

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

GCD(1, 858) = 858 / 858

GCD(1, 858) = 1

GCD of 77, 182, 127, 858 is 1
