Given numbers are 645, 635, 618, 320

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 635 are 5 x 127

Prime factors of 618 are 2 x 3 x 103

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 645, 635, 618, 320

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

Apply this formula for all numbers.

Step1:

LCM(645, 635) = 81915

GCD(645, 635) = ( 645 x 635 ) / 81915

= 645 / 635

= 645

Step2:

LCM(5, 618) = 3090

GCD(5, 618) = ( 5 x 618 ) / 3090

= 5 / 618

= 5

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 645, 635, 618, 320 is 1
