Given numbers are 802, 988, 621, 920

The list of prime factors of all numbers are

Prime factors of 802 are 2 x 401

Prime factors of 988 are 2 x 2 x 13 x 19

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

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

Given numbers are 802, 988, 621, 920

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

Apply this formula for all numbers.

Step1:

LCM(802, 988) = 396188

GCD(802, 988) = ( 802 x 988 ) / 396188

= 802 / 988

= 802

Step2:

LCM(2, 621) = 1242

GCD(2, 621) = ( 2 x 621 ) / 1242

= 2 / 621

= 2

Step3:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

So, Greatest Common Divisor of 802, 988, 621, 920 is 1
