GCD of numbers is the greatest common divisor

So, the GCD (231, 246, 235, 420) = 1.

Given numbers are 231, 246, 235, 420

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

Prime factors of 246 are 2 x 3 x 41

Prime factors of 235 are 5 x 47

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

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

Given numbers are 231, 246, 235, 420

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

Apply this formula for all numbers.

Step1:

LCM(231, 246) = 18942

GCD(231, 246) = ( 231 x 246 ) / 18942

= 231 / 246

= 231

Step2:

LCM(3, 235) = 705

GCD(3, 235) = ( 3 x 235 ) / 705

= 3 / 235

= 3

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 231, 246, 235, 420 is 1
