Given numbers are 840, 190, 489, 401

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 190 are 2 x 5 x 19

Prime factors of 489 are 3 x 163

Prime factors of 401 are 401

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

Given numbers are 840, 190, 489, 401

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

Apply this formula for all numbers.

Step1:

LCM(840, 190) = 15960

GCD(840, 190) = ( 840 x 190 ) / 15960

= 840 / 190

= 840

Step2:

LCM(10, 489) = 4890

GCD(10, 489) = ( 10 x 489 ) / 4890

= 10 / 489

= 10

Step3:

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

= 1 / 401

= 1

So, Greatest Common Divisor of 840, 190, 489, 401 is 1
