Given numbers are 115, 143, 342, 288

The list of prime factors of all numbers are

Prime factors of 115 are 5 x 23

Prime factors of 143 are 11 x 13

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

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

Given numbers are 115, 143, 342, 288

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

Apply this formula for all numbers.

Step1:

LCM(115, 143) = 16445

GCD(115, 143) = ( 115 x 143 ) / 16445

= 115 / 143

= 115

Step2:

LCM(1, 342) = 342

GCD(1, 342) = ( 1 x 342 ) / 342

= 1 / 342

= 1

Step3:

LCM(1, 288) = 288

GCD(1, 288) = ( 1 x 288 ) / 288

= 1 / 288

= 1

So, Greatest Common Divisor of 115, 143, 342, 288 is 1
