Given numbers are 638, 980, 357, 866

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 357 are 3 x 7 x 17

Prime factors of 866 are 2 x 433

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

Given numbers are 638, 980, 357, 866

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

Apply this formula for all numbers.

Step1:

LCM(638, 980) = 312620

GCD(638, 980) = ( 638 x 980 ) / 312620

= 638 / 980

= 638

Step2:

LCM(2, 357) = 714

GCD(2, 357) = ( 2 x 357 ) / 714

= 2 / 357

= 2

Step3:

LCM(1, 866) = 866

GCD(1, 866) = ( 1 x 866 ) / 866

= 1 / 866

= 1

So, Greatest Common Divisor of 638, 980, 357, 866 is 1
