Given numbers are 580, 876, 820, 821

The list of prime factors of all numbers are

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 876 are 2 x 2 x 3 x 73

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

Prime factors of 821 are 821

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

Given numbers are 580, 876, 820, 821

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

Apply this formula for all numbers.

Step1:

LCM(580, 876) = 127020

GCD(580, 876) = ( 580 x 876 ) / 127020

= 580 / 876

= 580

Step2:

LCM(4, 820) = 820

GCD(4, 820) = ( 4 x 820 ) / 820

= 4 / 820

= 4

Step3:

LCM(4, 821) = 3284

GCD(4, 821) = ( 4 x 821 ) / 3284

= 4 / 821

= 4

So, Greatest Common Divisor of 580, 876, 820, 821 is 1
