Given numbers are 410, 198, 678, 243

The list of prime factors of all numbers are

Prime factors of 410 are 2 x 5 x 41

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

Prime factors of 678 are 2 x 3 x 113

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

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

Given numbers are 410, 198, 678, 243

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

Apply this formula for all numbers.

Step1:

LCM(410, 198) = 40590

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

= 410 / 198

= 410

Step2:

LCM(2, 678) = 678

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

= 2 / 678

= 2

Step3:

LCM(2, 243) = 486

GCD(2, 243) = ( 2 x 243 ) / 486

= 2 / 243

= 2

So, Greatest Common Divisor of 410, 198, 678, 243 is 1
