Therefore, GCD of numbers 665, 635, 51, 179 is 1

Given Input Data is 665, 635, 51, 179

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

Prime Factorization of 665 is 5 x 7 x 19

Prime Factorization of 635 is 5 x 127

Prime Factorization of 51 is 3 x 17

Prime Factorization of 179 is 179

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(665, 635) = 84455

GCD(665, 635) = ( 665 x 635 ) / 84455

GCD(665, 635) = 422275 / 84455

GCD(665, 635) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 51

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

LCM(5, 51) = 255

GCD(5, 51) = ( 5 x 51 ) / 255

GCD(5, 51) = 255 / 255

GCD(5, 51) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 179

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

LCM(1, 179) = 179

GCD(1, 179) = ( 1 x 179 ) / 179

GCD(1, 179) = 179 / 179

GCD(1, 179) = 1

GCD of 665, 635, 51, 179 is 1
