So, the GCD (820, 364, 63, 855) = 1.

Given numbers are 820, 364, 63, 855

The list of prime factors of all numbers are

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

Prime factors of 364 are 2 x 2 x 7 x 13

Prime factors of 63 are 3 x 3 x 7

Prime factors of 855 are 3 x 3 x 5 x 19

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

Given numbers are 820, 364, 63, 855

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

Apply this formula for all numbers.

Step1:

LCM(820, 364) = 74620

GCD(820, 364) = ( 820 x 364 ) / 74620

= 820 / 364

= 820

Step2:

LCM(4, 63) = 252

GCD(4, 63) = ( 4 x 63 ) / 252

= 4 / 63

= 4

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 820, 364, 63, 855 is 1
