Given numbers are 198, 410, 678, 247

The list of prime factors of all numbers are

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 410 are 2 x 5 x 41

Prime factors of 678 are 2 x 3 x 113

Prime factors of 247 are 13 x 19

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

Given numbers are 198, 410, 678, 247

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

Apply this formula for all numbers.

Step1:

LCM(198, 410) = 40590

GCD(198, 410) = ( 198 x 410 ) / 40590

= 198 / 410

= 198

Step2:

LCM(2, 678) = 678

GCD(2, 678) = ( 2 x 678 ) / 678

= 2 / 678

= 2

Step3:

LCM(2, 247) = 494

GCD(2, 247) = ( 2 x 247 ) / 494

= 2 / 247

= 2

So, Greatest Common Divisor of 198, 410, 678, 247 is 1
