Given numbers are 638, 655, 307, 476

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 655 are 5 x 131

Prime factors of 307 are 307

Prime factors of 476 are 2 x 2 x 7 x 17

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

Given numbers are 638, 655, 307, 476

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

Apply this formula for all numbers.

Step1:

LCM(638, 655) = 417890

GCD(638, 655) = ( 638 x 655 ) / 417890

= 638 / 655

= 638

Step2:

LCM(1, 307) = 307

GCD(1, 307) = ( 1 x 307 ) / 307

= 1 / 307

= 1

Step3:

LCM(1, 476) = 476

GCD(1, 476) = ( 1 x 476 ) / 476

= 1 / 476

= 1

So, Greatest Common Divisor of 638, 655, 307, 476 is 1
