Given numbers are 121, 142, 222, 768

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 142 are 2 x 71

Prime factors of 222 are 2 x 3 x 37

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 121, 142, 222, 768

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

Apply this formula for all numbers.

Step1:

LCM(121, 142) = 17182

GCD(121, 142) = ( 121 x 142 ) / 17182

= 121 / 142

= 121

Step2:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

Step3:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

So, Greatest Common Divisor of 121, 142, 222, 768 is 1
