Given numbers are 843, 538, 851, 440

The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 538 are 2 x 269

Prime factors of 851 are 23 x 37

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 843, 538, 851, 440

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

Apply this formula for all numbers.

Step1:

LCM(843, 538) = 453534

GCD(843, 538) = ( 843 x 538 ) / 453534

= 843 / 538

= 843

Step2:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 843, 538, 851, 440 is 1
