Given numbers are 820, 915, 585, 619

The list of prime factors of all numbers are

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

Prime factors of 915 are 3 x 5 x 61

Prime factors of 585 are 3 x 3 x 5 x 13

Prime factors of 619 are 619

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

Given numbers are 820, 915, 585, 619

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

Apply this formula for all numbers.

Step1:

LCM(820, 915) = 150060

GCD(820, 915) = ( 820 x 915 ) / 150060

= 820 / 915

= 820

Step2:

LCM(5, 585) = 585

GCD(5, 585) = ( 5 x 585 ) / 585

= 5 / 585

= 5

Step3:

LCM(5, 619) = 3095

GCD(5, 619) = ( 5 x 619 ) / 3095

= 5 / 619

= 5

So, Greatest Common Divisor of 820, 915, 585, 619 is 1
