Given numbers are 645, 519, 907, 636

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 519 are 3 x 173

Prime factors of 907 are 907

Prime factors of 636 are 2 x 2 x 3 x 53

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

Given numbers are 645, 519, 907, 636

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

Apply this formula for all numbers.

Step1:

LCM(645, 519) = 111585

GCD(645, 519) = ( 645 x 519 ) / 111585

= 645 / 519

= 645

Step2:

LCM(3, 907) = 2721

GCD(3, 907) = ( 3 x 907 ) / 2721

= 3 / 907

= 3

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 645, 519, 907, 636 is 1
