Given numbers are 405, 503, 516, 771

The list of prime factors of all numbers are

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 503 are 503

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

Prime factors of 771 are 3 x 257

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

Given numbers are 405, 503, 516, 771

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

Apply this formula for all numbers.

Step1:

LCM(405, 503) = 203715

GCD(405, 503) = ( 405 x 503 ) / 203715

= 405 / 503

= 405

Step2:

LCM(1, 516) = 516

GCD(1, 516) = ( 1 x 516 ) / 516

= 1 / 516

= 1

Step3:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

So, Greatest Common Divisor of 405, 503, 516, 771 is 1
