Given numbers are 981, 342, 628, 756

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 628 are 2 x 2 x 157

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

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

Given numbers are 981, 342, 628, 756

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

Apply this formula for all numbers.

Step1:

LCM(981, 342) = 37278

GCD(981, 342) = ( 981 x 342 ) / 37278

= 981 / 342

= 981

Step2:

LCM(9, 628) = 5652

GCD(9, 628) = ( 9 x 628 ) / 5652

= 9 / 628

= 9

Step3:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

So, Greatest Common Divisor of 981, 342, 628, 756 is 1
