Therefore, GCD of numbers 644, 708, 549, 476 is 1

Given Input Data is 644, 708, 549, 476

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

Prime Factorization of 644 is 2 x 2 x 7 x 23

Prime Factorization of 708 is 2 x 2 x 3 x 59

Prime Factorization of 549 is 3 x 3 x 61

Prime Factorization of 476 is 2 x 2 x 7 x 17

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(644, 708) = 113988

GCD(644, 708) = ( 644 x 708 ) / 113988

GCD(644, 708) = 455952 / 113988

GCD(644, 708) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 549

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

LCM(4, 549) = 2196

GCD(4, 549) = ( 4 x 549 ) / 2196

GCD(4, 549) = 2196 / 2196

GCD(4, 549) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 476

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

LCM(1, 476) = 476

GCD(1, 476) = ( 1 x 476 ) / 476

GCD(1, 476) = 476 / 476

GCD(1, 476) = 1

GCD of 644, 708, 549, 476 is 1
