Therefore, GCD of numbers 651, 381, 15, 584 is 1

Given Input Data is 651, 381, 15, 584

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

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 381 is 3 x 127

Prime Factorization of 15 is 3 x 5

Prime Factorization of 584 is 2 x 2 x 2 x 73

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(651, 381) = 82677

GCD(651, 381) = ( 651 x 381 ) / 82677

GCD(651, 381) = 248031 / 82677

GCD(651, 381) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 15

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

LCM(3, 15) = 15

GCD(3, 15) = ( 3 x 15 ) / 15

GCD(3, 15) = 45 / 15

GCD(3, 15) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 584

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

LCM(3, 584) = 1752

GCD(3, 584) = ( 3 x 584 ) / 1752

GCD(3, 584) = 1752 / 1752

GCD(3, 584) = 1

GCD of 651, 381, 15, 584 is 1
