Given numbers are 421, 420, 50

The list of prime factors of all numbers are

Prime factors of 421 are 421

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

Prime factors of 50 are 2 x 5 x 5

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

Given numbers are 421, 420, 50

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

Apply this formula for all numbers.

Step1:

LCM(421, 420) = 176820

GCD(421, 420) = ( 421 x 420 ) / 176820

= 421 / 420

= 421

Step2:

LCM(1, 50) = 50

GCD(1, 50) = ( 1 x 50 ) / 50

= 1 / 50

= 1

So, Greatest Common Divisor of 421, 420, 50 is 1
