Given numbers are 400, 936, 861, 843

The list of prime factors of all numbers are

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 936 are 2 x 2 x 2 x 3 x 3 x 13

Prime factors of 861 are 3 x 7 x 41

Prime factors of 843 are 3 x 281

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

Given numbers are 400, 936, 861, 843

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

Apply this formula for all numbers.

Step1:

LCM(400, 936) = 46800

GCD(400, 936) = ( 400 x 936 ) / 46800

= 400 / 936

= 400

Step2:

LCM(8, 861) = 6888

GCD(8, 861) = ( 8 x 861 ) / 6888

= 8 / 861

= 8

Step3:

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

= 1 / 843

= 1

So, Greatest Common Divisor of 400, 936, 861, 843 is 1
