Given numbers are 840, 191, 390, 569

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 191 are 191

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

Prime factors of 569 are 569

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

Given numbers are 840, 191, 390, 569

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

Apply this formula for all numbers.

Step1:

LCM(840, 191) = 160440

GCD(840, 191) = ( 840 x 191 ) / 160440

= 840 / 191

= 840

Step2:

LCM(1, 390) = 390

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

= 1 / 390

= 1

Step3:

LCM(1, 569) = 569

GCD(1, 569) = ( 1 x 569 ) / 569

= 1 / 569

= 1

So, Greatest Common Divisor of 840, 191, 390, 569 is 1
