Given numbers are 680, 115, 857, 766

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 115 are 5 x 23

Prime factors of 857 are 857

Prime factors of 766 are 2 x 383

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

Given numbers are 680, 115, 857, 766

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

Apply this formula for all numbers.

Step1:

LCM(680, 115) = 15640

GCD(680, 115) = ( 680 x 115 ) / 15640

= 680 / 115

= 680

Step2:

LCM(5, 857) = 4285

GCD(5, 857) = ( 5 x 857 ) / 4285

= 5 / 857

= 5

Step3:

LCM(1, 766) = 766

GCD(1, 766) = ( 1 x 766 ) / 766

= 1 / 766

= 1

So, Greatest Common Divisor of 680, 115, 857, 766 is 1
