Given numbers are 685, 109, 770, 876

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 109 are 109

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 876 are 2 x 2 x 3 x 73

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

Given numbers are 685, 109, 770, 876

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

Apply this formula for all numbers.

Step1:

LCM(685, 109) = 74665

GCD(685, 109) = ( 685 x 109 ) / 74665

= 685 / 109

= 685

Step2:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

Step3:

LCM(1, 876) = 876

GCD(1, 876) = ( 1 x 876 ) / 876

= 1 / 876

= 1

So, Greatest Common Divisor of 685, 109, 770, 876 is 1
