Given numbers are 543, 555, 645, 650

The list of prime factors of all numbers are

Prime factors of 543 are 3 x 181

Prime factors of 555 are 3 x 5 x 37

Prime factors of 645 are 3 x 5 x 43

Prime factors of 650 are 2 x 5 x 5 x 13

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

Given numbers are 543, 555, 645, 650

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

Apply this formula for all numbers.

Step1:

LCM(543, 555) = 100455

GCD(543, 555) = ( 543 x 555 ) / 100455

= 543 / 555

= 543

Step2:

LCM(3, 645) = 645

GCD(3, 645) = ( 3 x 645 ) / 645

= 3 / 645

= 3

Step3:

LCM(3, 650) = 1950

GCD(3, 650) = ( 3 x 650 ) / 1950

= 3 / 650

= 3

So, Greatest Common Divisor of 543, 555, 645, 650 is 1
