Therefore, GCD of numbers 501, 987, 161, 417 is 1

Given Input Data is 501, 987, 161, 417

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

Prime Factorization of 501 is 3 x 167

Prime Factorization of 987 is 3 x 7 x 47

Prime Factorization of 161 is 7 x 23

Prime Factorization of 417 is 3 x 139

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(501, 987) = 164829

GCD(501, 987) = ( 501 x 987 ) / 164829

GCD(501, 987) = 494487 / 164829

GCD(501, 987) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 161

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

LCM(3, 161) = 483

GCD(3, 161) = ( 3 x 161 ) / 483

GCD(3, 161) = 483 / 483

GCD(3, 161) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 417

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

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

GCD(1, 417) = 417 / 417

GCD(1, 417) = 1

GCD of 501, 987, 161, 417 is 1
