Given numbers are 143, 341, 198, 390

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

Prime factors of 341 are 11 x 31

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

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 143, 341, 198, 390

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

Apply this formula for all numbers.

Step1:

LCM(143, 341) = 4433

GCD(143, 341) = ( 143 x 341 ) / 4433

= 143 / 341

= 143

Step2:

LCM(11, 198) = 198

GCD(11, 198) = ( 11 x 198 ) / 198

= 11 / 198

= 11

Step3:

LCM(11, 390) = 4290

GCD(11, 390) = ( 11 x 390 ) / 4290

= 11 / 390

= 11

So, Greatest Common Divisor of 143, 341, 198, 390 is 1
