Given numbers are 420, 329, 371, 206

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 329 are 7 x 47

Prime factors of 371 are 7 x 53

Prime factors of 206 are 2 x 103

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

Given numbers are 420, 329, 371, 206

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

Apply this formula for all numbers.

Step1:

LCM(420, 329) = 19740

GCD(420, 329) = ( 420 x 329 ) / 19740

= 420 / 329

= 420

Step2:

LCM(7, 371) = 371

GCD(7, 371) = ( 7 x 371 ) / 371

= 7 / 371

= 7

Step3:

LCM(7, 206) = 1442

GCD(7, 206) = ( 7 x 206 ) / 1442

= 7 / 206

= 7

So, Greatest Common Divisor of 420, 329, 371, 206 is 1
