Given numbers are 680, 988, 147, 785

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 988 are 2 x 2 x 13 x 19

Prime factors of 147 are 3 x 7 x 7

Prime factors of 785 are 5 x 157

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

Given numbers are 680, 988, 147, 785

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

Apply this formula for all numbers.

Step1:

LCM(680, 988) = 167960

GCD(680, 988) = ( 680 x 988 ) / 167960

= 680 / 988

= 680

Step2:

LCM(4, 147) = 588

GCD(4, 147) = ( 4 x 147 ) / 588

= 4 / 147

= 4

Step3:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

So, Greatest Common Divisor of 680, 988, 147, 785 is 1
