Given numbers are 721, 243, 612, 122

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

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

Prime factors of 122 are 2 x 61

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

Given numbers are 721, 243, 612, 122

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

Apply this formula for all numbers.

Step1:

LCM(721, 243) = 175203

GCD(721, 243) = ( 721 x 243 ) / 175203

= 721 / 243

= 721

Step2:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

Step3:

LCM(1, 122) = 122

GCD(1, 122) = ( 1 x 122 ) / 122

= 1 / 122

= 1

So, Greatest Common Divisor of 721, 243, 612, 122 is 1
