Given numbers are 865, 243, 135, 270

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

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

Prime factors of 135 are 3 x 3 x 3 x 5

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

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

Given numbers are 865, 243, 135, 270

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

Apply this formula for all numbers.

Step1:

LCM(865, 243) = 210195

GCD(865, 243) = ( 865 x 243 ) / 210195

= 865 / 243

= 865

Step2:

LCM(1, 135) = 135

GCD(1, 135) = ( 1 x 135 ) / 135

= 1 / 135

= 1

Step3:

LCM(1, 270) = 270

GCD(1, 270) = ( 1 x 270 ) / 270

= 1 / 270

= 1

So, Greatest Common Divisor of 865, 243, 135, 270 is 1
