Given numbers are 503, 456, 91, 820

The list of prime factors of all numbers are

Prime factors of 503 are 503

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 91 are 7 x 13

Prime factors of 820 are 2 x 2 x 5 x 41

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

Given numbers are 503, 456, 91, 820

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

Apply this formula for all numbers.

Step1:

LCM(503, 456) = 229368

GCD(503, 456) = ( 503 x 456 ) / 229368

= 503 / 456

= 503

Step2:

LCM(1, 91) = 91

GCD(1, 91) = ( 1 x 91 ) / 91

= 1 / 91

= 1

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 503, 456, 91, 820 is 1
