Given numbers are 385, 215, 108, 621

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 215 are 5 x 43

Prime factors of 108 are 2 x 2 x 3 x 3 x 3

Prime factors of 621 are 3 x 3 x 3 x 23

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

Given numbers are 385, 215, 108, 621

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

Apply this formula for all numbers.

Step1:

LCM(385, 215) = 16555

GCD(385, 215) = ( 385 x 215 ) / 16555

= 385 / 215

= 385

Step2:

LCM(5, 108) = 540

GCD(5, 108) = ( 5 x 108 ) / 540

= 5 / 108

= 5

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 385, 215, 108, 621 is 1
