Given numbers are 290, 258, 865, 390

The list of prime factors of all numbers are

Prime factors of 290 are 2 x 5 x 29

Prime factors of 258 are 2 x 3 x 43

Prime factors of 865 are 5 x 173

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 290, 258, 865, 390

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

Apply this formula for all numbers.

Step1:

LCM(290, 258) = 37410

GCD(290, 258) = ( 290 x 258 ) / 37410

= 290 / 258

= 290

Step2:

LCM(2, 865) = 1730

GCD(2, 865) = ( 2 x 865 ) / 1730

= 2 / 865

= 2

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 290, 258, 865, 390 is 1
