Given numbers are 819, 742, 612, 121

The list of prime factors of all numbers are

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 742 are 2 x 7 x 53

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 121 are 11 x 11

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

Given numbers are 819, 742, 612, 121

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

Apply this formula for all numbers.

Step1:

LCM(819, 742) = 86814

GCD(819, 742) = ( 819 x 742 ) / 86814

= 819 / 742

= 819

Step2:

LCM(7, 612) = 4284

GCD(7, 612) = ( 7 x 612 ) / 4284

= 7 / 612

= 7

Step3:

LCM(1, 121) = 121

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

= 1 / 121

= 1

So, Greatest Common Divisor of 819, 742, 612, 121 is 1
