Therefore, GCD of numbers 669, 945, 62, 130 is 1

Given Input Data is 669, 945, 62, 130

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

Prime Factorization of 669 is 3 x 223

Prime Factorization of 945 is 3 x 3 x 3 x 5 x 7

Prime Factorization of 62 is 2 x 31

Prime Factorization of 130 is 2 x 5 x 13

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(669, 945) = 210735

GCD(669, 945) = ( 669 x 945 ) / 210735

GCD(669, 945) = 632205 / 210735

GCD(669, 945) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 62

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

LCM(3, 62) = 186

GCD(3, 62) = ( 3 x 62 ) / 186

GCD(3, 62) = 186 / 186

GCD(3, 62) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 130

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

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

GCD(1, 130) = 130 / 130

GCD(1, 130) = 1

GCD of 669, 945, 62, 130 is 1
