Given numbers are 515, 511, 368, 820

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 511 are 7 x 73

Prime factors of 368 are 2 x 2 x 2 x 2 x 23

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 515, 511, 368, 820

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

Apply this formula for all numbers.

Step1:

LCM(515, 511) = 263165

GCD(515, 511) = ( 515 x 511 ) / 263165

= 515 / 511

= 515

Step2:

LCM(1, 368) = 368

GCD(1, 368) = ( 1 x 368 ) / 368

= 1 / 368

= 1

Step3:

LCM(1, 820) = 820

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

= 1 / 820

= 1

So, Greatest Common Divisor of 515, 511, 368, 820 is 1
