Given numbers are 390, 321, 850, 715

The list of prime factors of all numbers are

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

Prime factors of 321 are 3 x 107

Prime factors of 850 are 2 x 5 x 5 x 17

Prime factors of 715 are 5 x 11 x 13

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

Given numbers are 390, 321, 850, 715

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

Apply this formula for all numbers.

Step1:

LCM(390, 321) = 41730

GCD(390, 321) = ( 390 x 321 ) / 41730

= 390 / 321

= 390

Step2:

LCM(3, 850) = 2550

GCD(3, 850) = ( 3 x 850 ) / 2550

= 3 / 850

= 3

Step3:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

So, Greatest Common Divisor of 390, 321, 850, 715 is 1
