Given numbers are 742, 855, 192, 243

The list of prime factors of all numbers are

Prime factors of 742 are 2 x 7 x 53

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 192 are 2 x 2 x 2 x 2 x 2 x 2 x 3

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

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

Given numbers are 742, 855, 192, 243

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

Apply this formula for all numbers.

Step1:

LCM(742, 855) = 634410

GCD(742, 855) = ( 742 x 855 ) / 634410

= 742 / 855

= 742

Step2:

LCM(1, 192) = 192

GCD(1, 192) = ( 1 x 192 ) / 192

= 1 / 192

= 1

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 742, 855, 192, 243 is 1
