Given numbers are 819, 355, 520, 124

The list of prime factors of all numbers are

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 355 are 5 x 71

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 124 are 2 x 2 x 31

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

Given numbers are 819, 355, 520, 124

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

Apply this formula for all numbers.

Step1:

LCM(819, 355) = 290745

GCD(819, 355) = ( 819 x 355 ) / 290745

= 819 / 355

= 819

Step2:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

Step3:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

So, Greatest Common Divisor of 819, 355, 520, 124 is 1
