Given numbers are 686, 620, 631, 235

The list of prime factors of all numbers are

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 631 are 631

Prime factors of 235 are 5 x 47

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

Given numbers are 686, 620, 631, 235

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

Apply this formula for all numbers.

Step1:

LCM(686, 620) = 212660

GCD(686, 620) = ( 686 x 620 ) / 212660

= 686 / 620

= 686

Step2:

LCM(2, 631) = 1262

GCD(2, 631) = ( 2 x 631 ) / 1262

= 2 / 631

= 2

Step3:

LCM(1, 235) = 235

GCD(1, 235) = ( 1 x 235 ) / 235

= 1 / 235

= 1

So, Greatest Common Divisor of 686, 620, 631, 235 is 1
