Given numbers are 680, 813, 542, 142

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 813 are 3 x 271

Prime factors of 542 are 2 x 271

Prime factors of 142 are 2 x 71

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

Given numbers are 680, 813, 542, 142

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

Apply this formula for all numbers.

Step1:

LCM(680, 813) = 552840

GCD(680, 813) = ( 680 x 813 ) / 552840

= 680 / 813

= 680

Step2:

LCM(1, 542) = 542

GCD(1, 542) = ( 1 x 542 ) / 542

= 1 / 542

= 1

Step3:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

So, Greatest Common Divisor of 680, 813, 542, 142 is 1
