Given numbers are 108, 280, 747, 644

The list of prime factors of all numbers are

Prime factors of 108 are 2 x 2 x 3 x 3 x 3

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 747 are 3 x 3 x 83

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 108, 280, 747, 644

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

Apply this formula for all numbers.

Step1:

LCM(108, 280) = 7560

GCD(108, 280) = ( 108 x 280 ) / 7560

= 108 / 280

= 108

Step2:

LCM(4, 747) = 2988

GCD(4, 747) = ( 4 x 747 ) / 2988

= 4 / 747

= 4

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 108, 280, 747, 644 is 1
