Given numbers are 843, 404, 874, 640

The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 404 are 2 x 2 x 101

Prime factors of 874 are 2 x 19 x 23

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 843, 404, 874, 640

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

Apply this formula for all numbers.

Step1:

LCM(843, 404) = 340572

GCD(843, 404) = ( 843 x 404 ) / 340572

= 843 / 404

= 843

Step2:

LCM(1, 874) = 874

GCD(1, 874) = ( 1 x 874 ) / 874

= 1 / 874

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 843, 404, 874, 640 is 1
