Given numbers are 102, 686, 628, 803

The list of prime factors of all numbers are

Prime factors of 102 are 2 x 3 x 17

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

Prime factors of 628 are 2 x 2 x 157

Prime factors of 803 are 11 x 73

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

Given numbers are 102, 686, 628, 803

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

Apply this formula for all numbers.

Step1:

LCM(102, 686) = 34986

GCD(102, 686) = ( 102 x 686 ) / 34986

= 102 / 686

= 102

Step2:

LCM(2, 628) = 628

GCD(2, 628) = ( 2 x 628 ) / 628

= 2 / 628

= 2

Step3:

LCM(2, 803) = 1606

GCD(2, 803) = ( 2 x 803 ) / 1606

= 2 / 803

= 2

So, Greatest Common Divisor of 102, 686, 628, 803 is 1
