Prime factors of 417 are 3 x 139

Prime factors of 580 are 2 x 2 x 5 x 29

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

Given numbers are 491, 840, 417, 580

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

Apply this formula for all numbers.

Step1:

LCM(491, 840) = 412440

GCD(491, 840) = ( 491 x 840 ) / 412440

= 491 / 840

= 491

Step2:

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

= 1 / 417

= 1

Step3:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

So, Greatest Common Divisor of 491, 840, 417, 580 is 1
