Given numbers are 503, 987, 660, 681

The list of prime factors of all numbers are

Prime factors of 503 are 503

Prime factors of 987 are 3 x 7 x 47

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 681 are 3 x 227

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

Given numbers are 503, 987, 660, 681

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

Apply this formula for all numbers.

Step1:

LCM(503, 987) = 496461

GCD(503, 987) = ( 503 x 987 ) / 496461

= 503 / 987

= 503

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

So, Greatest Common Divisor of 503, 987, 660, 681 is 1
