Given numbers are 620, 104, 557, 415

The list of prime factors of all numbers are

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

Prime factors of 104 are 2 x 2 x 2 x 13

Prime factors of 557 are 557

Prime factors of 415 are 5 x 83

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

Given numbers are 620, 104, 557, 415

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

Apply this formula for all numbers.

Step1:

LCM(620, 104) = 16120

GCD(620, 104) = ( 620 x 104 ) / 16120

= 620 / 104

= 620

Step2:

LCM(4, 557) = 2228

GCD(4, 557) = ( 4 x 557 ) / 2228

= 4 / 557

= 4

Step3:

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

= 1 / 415

= 1

So, Greatest Common Divisor of 620, 104, 557, 415 is 1
