Given numbers are 765, 843, 400, 543

The list of prime factors of all numbers are

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 843 are 3 x 281

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

Prime factors of 543 are 3 x 181

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

Given numbers are 765, 843, 400, 543

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

Apply this formula for all numbers.

Step1:

LCM(765, 843) = 214965

GCD(765, 843) = ( 765 x 843 ) / 214965

= 765 / 843

= 765

Step2:

LCM(3, 400) = 1200

GCD(3, 400) = ( 3 x 400 ) / 1200

= 3 / 400

= 3

Step3:

LCM(1, 543) = 543

GCD(1, 543) = ( 1 x 543 ) / 543

= 1 / 543

= 1

So, Greatest Common Divisor of 765, 843, 400, 543 is 1
