Given numbers are 212, 222, 391, 450

The list of prime factors of all numbers are

Prime factors of 212 are 2 x 2 x 53

Prime factors of 222 are 2 x 3 x 37

Prime factors of 391 are 17 x 23

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

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

Given numbers are 212, 222, 391, 450

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

Apply this formula for all numbers.

Step1:

LCM(212, 222) = 23532

GCD(212, 222) = ( 212 x 222 ) / 23532

= 212 / 222

= 212

Step2:

LCM(2, 391) = 782

GCD(2, 391) = ( 2 x 391 ) / 782

= 2 / 391

= 2

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 212, 222, 391, 450 is 1
