Given numbers are 981, 108, 754, 645

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

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

Prime factors of 754 are 2 x 13 x 29

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 981, 108, 754, 645

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

Apply this formula for all numbers.

Step1:

LCM(981, 108) = 11772

GCD(981, 108) = ( 981 x 108 ) / 11772

= 981 / 108

= 981

Step2:

LCM(9, 754) = 6786

GCD(9, 754) = ( 9 x 754 ) / 6786

= 9 / 754

= 9

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 981, 108, 754, 645 is 1
