Given numbers are 255, 387, 136, 812

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 387 are 3 x 3 x 43

Prime factors of 136 are 2 x 2 x 2 x 17

Prime factors of 812 are 2 x 2 x 7 x 29

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

Given numbers are 255, 387, 136, 812

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

Apply this formula for all numbers.

Step1:

LCM(255, 387) = 32895

GCD(255, 387) = ( 255 x 387 ) / 32895

= 255 / 387

= 255

Step2:

LCM(3, 136) = 408

GCD(3, 136) = ( 3 x 136 ) / 408

= 3 / 136

= 3

Step3:

LCM(1, 812) = 812

GCD(1, 812) = ( 1 x 812 ) / 812

= 1 / 812

= 1

So, Greatest Common Divisor of 255, 387, 136, 812 is 1
