Given numbers are 333, 161, 121, 420

The list of prime factors of all numbers are

Prime factors of 333 are 3 x 3 x 37

Prime factors of 161 are 7 x 23

Prime factors of 121 are 11 x 11

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

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

Given numbers are 333, 161, 121, 420

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

Apply this formula for all numbers.

Step1:

LCM(333, 161) = 53613

GCD(333, 161) = ( 333 x 161 ) / 53613

= 333 / 161

= 333

Step2:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 333, 161, 121, 420 is 1
