Given numbers are 680, 567, 198, 765

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 567 are 3 x 3 x 3 x 3 x 7

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 765 are 3 x 3 x 5 x 17

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

Given numbers are 680, 567, 198, 765

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

Apply this formula for all numbers.

Step1:

LCM(680, 567) = 385560

GCD(680, 567) = ( 680 x 567 ) / 385560

= 680 / 567

= 680

Step2:

LCM(1, 198) = 198

GCD(1, 198) = ( 1 x 198 ) / 198

= 1 / 198

= 1

Step3:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

So, Greatest Common Divisor of 680, 567, 198, 765 is 1
