Given numbers are 421, 446, 212, 408

The list of prime factors of all numbers are

Prime factors of 421 are 421

Prime factors of 446 are 2 x 223

Prime factors of 212 are 2 x 2 x 53

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

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

Given numbers are 421, 446, 212, 408

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

Apply this formula for all numbers.

Step1:

LCM(421, 446) = 187766

GCD(421, 446) = ( 421 x 446 ) / 187766

= 421 / 446

= 421

Step2:

LCM(1, 212) = 212

GCD(1, 212) = ( 1 x 212 ) / 212

= 1 / 212

= 1

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 421, 446, 212, 408 is 1
