Given numbers are 979, 660, 539, 643

The list of prime factors of all numbers are

Prime factors of 979 are 11 x 89

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 539 are 7 x 7 x 11

Prime factors of 643 are 643

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

Given numbers are 979, 660, 539, 643

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

Apply this formula for all numbers.

Step1:

LCM(979, 660) = 58740

GCD(979, 660) = ( 979 x 660 ) / 58740

= 979 / 660

= 979

Step2:

LCM(11, 539) = 539

GCD(11, 539) = ( 11 x 539 ) / 539

= 11 / 539

= 11

Step3:

LCM(11, 643) = 7073

GCD(11, 643) = ( 11 x 643 ) / 7073

= 11 / 643

= 11

So, Greatest Common Divisor of 979, 660, 539, 643 is 1
