Given numbers are 979, 973, 780, 685

The list of prime factors of all numbers are

Prime factors of 979 are 11 x 89

Prime factors of 973 are 7 x 139

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 685 are 5 x 137

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

Given numbers are 979, 973, 780, 685

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

Apply this formula for all numbers.

Step1:

LCM(979, 973) = 952567

GCD(979, 973) = ( 979 x 973 ) / 952567

= 979 / 973

= 979

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

So, Greatest Common Divisor of 979, 973, 780, 685 is 1
