Given numbers are 390, 665, 205, 418

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 665 are 5 x 7 x 19

Prime factors of 205 are 5 x 41

Prime factors of 418 are 2 x 11 x 19

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

Given numbers are 390, 665, 205, 418

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

Apply this formula for all numbers.

Step1:

LCM(390, 665) = 51870

GCD(390, 665) = ( 390 x 665 ) / 51870

= 390 / 665

= 390

Step2:

LCM(5, 205) = 205

GCD(5, 205) = ( 5 x 205 ) / 205

= 5 / 205

= 5

Step3:

LCM(5, 418) = 2090

GCD(5, 418) = ( 5 x 418 ) / 2090

= 5 / 418

= 5

So, Greatest Common Divisor of 390, 665, 205, 418 is 1
