Given numbers are 110, 129, 643, 394

The list of prime factors of all numbers are

Prime factors of 110 are 2 x 5 x 11

Prime factors of 129 are 3 x 43

Prime factors of 643 are 643

Prime factors of 394 are 2 x 197

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

Given numbers are 110, 129, 643, 394

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

Apply this formula for all numbers.

Step1:

LCM(110, 129) = 14190

GCD(110, 129) = ( 110 x 129 ) / 14190

= 110 / 129

= 110

Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

Step3:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

So, Greatest Common Divisor of 110, 129, 643, 394 is 1
