Given numbers are 678, 356, 191, 470

The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 356 are 2 x 2 x 89

Prime factors of 191 are 191

Prime factors of 470 are 2 x 5 x 47

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

Given numbers are 678, 356, 191, 470

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

Apply this formula for all numbers.

Step1:

LCM(678, 356) = 120684

GCD(678, 356) = ( 678 x 356 ) / 120684

= 678 / 356

= 678

Step2:

LCM(2, 191) = 382

GCD(2, 191) = ( 2 x 191 ) / 382

= 2 / 191

= 2

Step3:

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

= 1 / 470

= 1

So, Greatest Common Divisor of 678, 356, 191, 470 is 1
