Given numbers are 678, 458, 378, 115

The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 458 are 2 x 229

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

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 678, 458, 378, 115

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

Apply this formula for all numbers.

Step1:

LCM(678, 458) = 155262

GCD(678, 458) = ( 678 x 458 ) / 155262

= 678 / 458

= 678

Step2:

LCM(2, 378) = 378

GCD(2, 378) = ( 2 x 378 ) / 378

= 2 / 378

= 2

Step3:

LCM(2, 115) = 230

GCD(2, 115) = ( 2 x 115 ) / 230

= 2 / 115

= 2

So, Greatest Common Divisor of 678, 458, 378, 115 is 1
