Given numbers are 243, 720, 119, 755

The list of prime factors of all numbers are

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

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 119 are 7 x 17

Prime factors of 755 are 5 x 151

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

Given numbers are 243, 720, 119, 755

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

Apply this formula for all numbers.

Step1:

LCM(243, 720) = 19440

GCD(243, 720) = ( 243 x 720 ) / 19440

= 243 / 720

= 243

Step2:

LCM(9, 119) = 1071

GCD(9, 119) = ( 9 x 119 ) / 1071

= 9 / 119

= 9

Step3:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

So, Greatest Common Divisor of 243, 720, 119, 755 is 1
