Given numbers are 870, 637, 802, 641

The list of prime factors of all numbers are

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 637 are 7 x 7 x 13

Prime factors of 802 are 2 x 401

Prime factors of 641 are 641

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

Given numbers are 870, 637, 802, 641

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

Apply this formula for all numbers.

Step1:

LCM(870, 637) = 554190

GCD(870, 637) = ( 870 x 637 ) / 554190

= 870 / 637

= 870

Step2:

LCM(1, 802) = 802

GCD(1, 802) = ( 1 x 802 ) / 802

= 1 / 802

= 1

Step3:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

So, Greatest Common Divisor of 870, 637, 802, 641 is 1
