Given numbers are 198, 646, 341, 121

The list of prime factors of all numbers are

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

Prime factors of 646 are 2 x 17 x 19

Prime factors of 341 are 11 x 31

Prime factors of 121 are 11 x 11

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

Given numbers are 198, 646, 341, 121

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

Apply this formula for all numbers.

Step1:

LCM(198, 646) = 63954

GCD(198, 646) = ( 198 x 646 ) / 63954

= 198 / 646

= 198

Step2:

LCM(2, 341) = 682

GCD(2, 341) = ( 2 x 341 ) / 682

= 2 / 341

= 2

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 198, 646, 341, 121 is 1
