Given numbers are 390, 214, 564, 287

The list of prime factors of all numbers are

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

Prime factors of 214 are 2 x 107

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 287 are 7 x 41

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

Given numbers are 390, 214, 564, 287

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

Apply this formula for all numbers.

Step1:

LCM(390, 214) = 41730

GCD(390, 214) = ( 390 x 214 ) / 41730

= 390 / 214

= 390

Step2:

LCM(2, 564) = 564

GCD(2, 564) = ( 2 x 564 ) / 564

= 2 / 564

= 2

Step3:

LCM(2, 287) = 574

GCD(2, 287) = ( 2 x 287 ) / 574

= 2 / 287

= 2

So, Greatest Common Divisor of 390, 214, 564, 287 is 1
