Given numbers are 408, 490, 195, 117

The list of prime factors of all numbers are

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 195 are 3 x 5 x 13

Prime factors of 117 are 3 x 3 x 13

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

Given numbers are 408, 490, 195, 117

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

Apply this formula for all numbers.

Step1:

LCM(408, 490) = 99960

GCD(408, 490) = ( 408 x 490 ) / 99960

= 408 / 490

= 408

Step2:

LCM(2, 195) = 390

GCD(2, 195) = ( 2 x 195 ) / 390

= 2 / 195

= 2

Step3:

LCM(1, 117) = 117

GCD(1, 117) = ( 1 x 117 ) / 117

= 1 / 117

= 1

So, Greatest Common Divisor of 408, 490, 195, 117 is 1
