Given numbers are 820, 644, 517, 301

The list of prime factors of all numbers are

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

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 517 are 11 x 47

Prime factors of 301 are 7 x 43

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

Given numbers are 820, 644, 517, 301

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

Apply this formula for all numbers.

Step1:

LCM(820, 644) = 132020

GCD(820, 644) = ( 820 x 644 ) / 132020

= 820 / 644

= 820

Step2:

LCM(4, 517) = 2068

GCD(4, 517) = ( 4 x 517 ) / 2068

= 4 / 517

= 4

Step3:

LCM(1, 301) = 301

GCD(1, 301) = ( 1 x 301 ) / 301

= 1 / 301

= 1

So, Greatest Common Divisor of 820, 644, 517, 301 is 1
