Given numbers are 420, 120, 894, 397

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 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 894 are 2 x 3 x 149

Prime factors of 397 are 397

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

Given numbers are 420, 120, 894, 397

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

Apply this formula for all numbers.

Step1:

LCM(420, 120) = 840

GCD(420, 120) = ( 420 x 120 ) / 840

= 420 / 120

= 420

Step2:

LCM(60, 894) = 8940

GCD(60, 894) = ( 60 x 894 ) / 8940

= 60 / 894

= 60

Step3:

LCM(6, 397) = 2382

GCD(6, 397) = ( 6 x 397 ) / 2382

= 6 / 397

= 6

So, Greatest Common Divisor of 420, 120, 894, 397 is 1
