The list of prime factors of all numbers are

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

Prime factors of 607 are 607

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 262 are 2 x 131

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

Given numbers are 686, 607, 820, 262

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

Apply this formula for all numbers.

Step1:

LCM(686, 607) = 416402

GCD(686, 607) = ( 686 x 607 ) / 416402

= 686 / 607

= 686

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 262) = 262

GCD(1, 262) = ( 1 x 262 ) / 262

= 1 / 262

= 1

So, Greatest Common Divisor of 686, 607, 820, 262 is 1
