Given numbers are 665, 870, 213, 503

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

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

Prime factors of 213 are 3 x 71

Prime factors of 503 are 503

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

Given numbers are 665, 870, 213, 503

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

Apply this formula for all numbers.

Step1:

LCM(665, 870) = 115710

GCD(665, 870) = ( 665 x 870 ) / 115710

= 665 / 870

= 665

Step2:

LCM(5, 213) = 1065

GCD(5, 213) = ( 5 x 213 ) / 1065

= 5 / 213

= 5

Step3:

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

= 1 / 503

= 1

So, Greatest Common Divisor of 665, 870, 213, 503 is 1
