Therefore, GCD of numbers 368, 168, 125, 649 is 1

Given Input Data is 368, 168, 125, 649

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

Prime Factorization of 368 is 2 x 2 x 2 x 2 x 23

Prime Factorization of 168 is 2 x 2 x 2 x 3 x 7

Prime Factorization of 125 is 5 x 5 x 5

Prime Factorization of 649 is 11 x 59

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(368, 168) = 7728

GCD(368, 168) = ( 368 x 168 ) / 7728

GCD(368, 168) = 61824 / 7728

GCD(368, 168) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 125

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

LCM(8, 125) = 1000

GCD(8, 125) = ( 8 x 125 ) / 1000

GCD(8, 125) = 1000 / 1000

GCD(8, 125) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 649

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

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

GCD(1, 649) = 649 / 649

GCD(1, 649) = 1

GCD of 368, 168, 125, 649 is 1
