Given numbers are 638, 260, 605, 368

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 605 are 5 x 11 x 11

Prime factors of 368 are 2 x 2 x 2 x 2 x 23

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

Given numbers are 638, 260, 605, 368

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

Apply this formula for all numbers.

Step1:

LCM(638, 260) = 82940

GCD(638, 260) = ( 638 x 260 ) / 82940

= 638 / 260

= 638

Step2:

LCM(2, 605) = 1210

GCD(2, 605) = ( 2 x 605 ) / 1210

= 2 / 605

= 2

Step3:

LCM(1, 368) = 368

GCD(1, 368) = ( 1 x 368 ) / 368

= 1 / 368

= 1

So, Greatest Common Divisor of 638, 260, 605, 368 is 1
