Given numbers are 287, 240, 285, 258

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 285 are 3 x 5 x 19

Prime factors of 258 are 2 x 3 x 43

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

Given numbers are 287, 240, 285, 258

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

Apply this formula for all numbers.

Step1:

LCM(287, 240) = 68880

GCD(287, 240) = ( 287 x 240 ) / 68880

= 287 / 240

= 287

Step2:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

Step3:

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

= 1 / 258

= 1

So, Greatest Common Divisor of 287, 240, 285, 258 is 1
