Given numbers are 638, 540, 664, 875

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 875 are 5 x 5 x 5 x 7

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

Given numbers are 638, 540, 664, 875

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

Apply this formula for all numbers.

Step1:

LCM(638, 540) = 172260

GCD(638, 540) = ( 638 x 540 ) / 172260

= 638 / 540

= 638

Step2:

LCM(2, 664) = 664

GCD(2, 664) = ( 2 x 664 ) / 664

= 2 / 664

= 2

Step3:

LCM(2, 875) = 1750

GCD(2, 875) = ( 2 x 875 ) / 1750

= 2 / 875

= 2

So, Greatest Common Divisor of 638, 540, 664, 875 is 1
