Given numbers are 423, 934, 420, 918

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 934 are 2 x 467

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

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

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

Given numbers are 423, 934, 420, 918

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

Apply this formula for all numbers.

Step1:

LCM(423, 934) = 395082

GCD(423, 934) = ( 423 x 934 ) / 395082

= 423 / 934

= 423

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 918) = 918

GCD(1, 918) = ( 1 x 918 ) / 918

= 1 / 918

= 1

So, Greatest Common Divisor of 423, 934, 420, 918 is 1
