Given numbers are 788, 765, 121, 456

The list of prime factors of all numbers are

Prime factors of 788 are 2 x 2 x 197

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 121 are 11 x 11

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

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

Given numbers are 788, 765, 121, 456

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

Apply this formula for all numbers.

Step1:

LCM(788, 765) = 602820

GCD(788, 765) = ( 788 x 765 ) / 602820

= 788 / 765

= 788

Step2:

LCM(1, 121) = 121

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

= 1 / 121

= 1

Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

So, Greatest Common Divisor of 788, 765, 121, 456 is 1
