Given Input Data is 624, 140, 277, 215

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

Prime Factorization of 624 is 2 x 2 x 2 x 2 x 3 x 13

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

Prime Factorization of 277 is 277

Prime Factorization of 215 is 5 x 43

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(624, 140) = 21840

GCD(624, 140) = ( 624 x 140 ) / 21840

GCD(624, 140) = 87360 / 21840

GCD(624, 140) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 277

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

LCM(4, 277) = 1108

GCD(4, 277) = ( 4 x 277 ) / 1108

GCD(4, 277) = 1108 / 1108

GCD(4, 277) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 215

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

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

GCD(1, 215) = 215 / 215

GCD(1, 215) = 1

GCD of 624, 140, 277, 215 is 1
