Given Input Data is 464, 140, 28, 485

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

Prime Factorization of 464 is 2 x 2 x 2 x 2 x 29

Prime Factorization of 140 is 2 x 2 x 5 x 7

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 485 is 5 x 97

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(464, 140) = 16240

GCD(464, 140) = ( 464 x 140 ) / 16240

GCD(464, 140) = 64960 / 16240

GCD(464, 140) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 28

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

LCM(4, 28) = 28

GCD(4, 28) = ( 4 x 28 ) / 28

GCD(4, 28) = 112 / 28

GCD(4, 28) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 485

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

LCM(4, 485) = 1940

GCD(4, 485) = ( 4 x 485 ) / 1940

GCD(4, 485) = 1940 / 1940

GCD(4, 485) = 1

GCD of 464, 140, 28, 485 is 1
