Given numbers are 994, 642, 680, 831

The list of prime factors of all numbers are

Prime factors of 994 are 2 x 7 x 71

Prime factors of 642 are 2 x 3 x 107

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

Prime factors of 831 are 3 x 277

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

Given numbers are 994, 642, 680, 831

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

Apply this formula for all numbers.

Step1:

LCM(994, 642) = 319074

GCD(994, 642) = ( 994 x 642 ) / 319074

= 994 / 642

= 994

Step2:

LCM(2, 680) = 680

GCD(2, 680) = ( 2 x 680 ) / 680

= 2 / 680

= 2

Step3:

LCM(2, 831) = 1662

GCD(2, 831) = ( 2 x 831 ) / 1662

= 2 / 831

= 2

So, Greatest Common Divisor of 994, 642, 680, 831 is 1
