Given numbers are 121, 333, 21

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 333 are 3 x 3 x 37

Prime factors of 21 are 3 x 7

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

Given numbers are 121, 333, 21

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

Apply this formula for all numbers.

Step1:

LCM(121, 333) = 40293

GCD(121, 333) = ( 121 x 333 ) / 40293

= 121 / 333

= 121

Step2:

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

= 1 / 21

= 1

So, Greatest Common Divisor of 121, 333, 21 is 1
