Therefore, GCD of numbers 676, 840, 671, 910 is 1

Given Input Data is 676, 840, 671, 910

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

Prime Factorization of 676 is 2 x 2 x 13 x 13

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

Prime Factorization of 671 is 11 x 61

Prime Factorization of 910 is 2 x 5 x 7 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(676, 840) = 141960

GCD(676, 840) = ( 676 x 840 ) / 141960

GCD(676, 840) = 567840 / 141960

GCD(676, 840) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 671

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

LCM(4, 671) = 2684

GCD(4, 671) = ( 4 x 671 ) / 2684

GCD(4, 671) = 2684 / 2684

GCD(4, 671) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 910

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

LCM(1, 910) = 910

GCD(1, 910) = ( 1 x 910 ) / 910

GCD(1, 910) = 910 / 910

GCD(1, 910) = 1

GCD of 676, 840, 671, 910 is 1
