Given numbers are 420, 427, 940, 238

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 427 are 7 x 61

Prime factors of 940 are 2 x 2 x 5 x 47

Prime factors of 238 are 2 x 7 x 17

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

Given numbers are 420, 427, 940, 238

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

Apply this formula for all numbers.

Step1:

LCM(420, 427) = 25620

GCD(420, 427) = ( 420 x 427 ) / 25620

= 420 / 427

= 420

Step2:

LCM(7, 940) = 6580

GCD(7, 940) = ( 7 x 940 ) / 6580

= 7 / 940

= 7

Step3:

LCM(1, 238) = 238

GCD(1, 238) = ( 1 x 238 ) / 238

= 1 / 238

= 1

So, Greatest Common Divisor of 420, 427, 940, 238 is 1
