Given numbers are 638, 180, 963, 720

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 963 are 3 x 3 x 107

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 638, 180, 963, 720

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(638, 180) = 57420

GCD(638, 180) = ( 638 x 180 ) / 57420

= 638 / 180

= 638

Step2:

LCM(2, 963) = 1926

GCD(2, 963) = ( 2 x 963 ) / 1926

= 2 / 963

= 2

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 638, 180, 963, 720 is 1
