Given numbers are 516, 780, 331, 503

The list of prime factors of all numbers are

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 331 are 331

Prime factors of 503 are 503

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

Given numbers are 516, 780, 331, 503

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

Apply this formula for all numbers.

Step1:

LCM(516, 780) = 33540

GCD(516, 780) = ( 516 x 780 ) / 33540

= 516 / 780

= 516

Step2:

LCM(12, 331) = 3972

GCD(12, 331) = ( 12 x 331 ) / 3972

= 12 / 331

= 12

Step3:

LCM(1, 503) = 503

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

= 1 / 503

= 1

So, Greatest Common Divisor of 516, 780, 331, 503 is 1
