Given numbers are 122, 581, 815, 620

The list of prime factors of all numbers are

Prime factors of 122 are 2 x 61

Prime factors of 581 are 7 x 83

Prime factors of 815 are 5 x 163

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 122, 581, 815, 620

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

Apply this formula for all numbers.

Step1:

LCM(122, 581) = 70882

GCD(122, 581) = ( 122 x 581 ) / 70882

= 122 / 581

= 122

Step2:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 122, 581, 815, 620 is 1
