Given numbers are 620, 351, 981, 902

The list of prime factors of all numbers are

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

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 981 are 3 x 3 x 109

Prime factors of 902 are 2 x 11 x 41

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

Given numbers are 620, 351, 981, 902

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

Apply this formula for all numbers.

Step1:

LCM(620, 351) = 217620

GCD(620, 351) = ( 620 x 351 ) / 217620

= 620 / 351

= 620

Step2:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

Step3:

LCM(1, 902) = 902

GCD(1, 902) = ( 1 x 902 ) / 902

= 1 / 902

= 1

So, Greatest Common Divisor of 620, 351, 981, 902 is 1
