Given numbers are 675, 654, 390, 115

The list of prime factors of all numbers are

Prime factors of 675 are 3 x 3 x 3 x 5 x 5

Prime factors of 654 are 2 x 3 x 109

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

Prime factors of 115 are 5 x 23

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

Given numbers are 675, 654, 390, 115

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

Apply this formula for all numbers.

Step1:

LCM(675, 654) = 147150

GCD(675, 654) = ( 675 x 654 ) / 147150

= 675 / 654

= 675

Step2:

LCM(3, 390) = 390

GCD(3, 390) = ( 3 x 390 ) / 390

= 3 / 390

= 3

Step3:

LCM(3, 115) = 345

GCD(3, 115) = ( 3 x 115 ) / 345

= 3 / 115

= 3

So, Greatest Common Divisor of 675, 654, 390, 115 is 1
