Given numbers are 605, 705, 678, 197

The list of prime factors of all numbers are

Prime factors of 605 are 5 x 11 x 11

Prime factors of 705 are 3 x 5 x 47

Prime factors of 678 are 2 x 3 x 113

Prime factors of 197 are 197

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

Given numbers are 605, 705, 678, 197

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

Apply this formula for all numbers.

Step1:

LCM(605, 705) = 85305

GCD(605, 705) = ( 605 x 705 ) / 85305

= 605 / 705

= 605

Step2:

LCM(5, 678) = 3390

GCD(5, 678) = ( 5 x 678 ) / 3390

= 5 / 678

= 5

Step3:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

So, Greatest Common Divisor of 605, 705, 678, 197 is 1
