Given numbers are 620, 447, 685, 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 447 are 3 x 149

Prime factors of 685 are 5 x 137

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, 447, 685, 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, 447) = 277140

GCD(620, 447) = ( 620 x 447 ) / 277140

= 620 / 447

= 620

Step2:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

Step3:

LCM(1, 415) = 415

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

= 1 / 415

= 1

So, Greatest Common Divisor of 620, 447, 685, 415 is 1
