The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 965 are 5 x 193

Prime factors of 447 are 3 x 149

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 645, 965, 447, 543

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

Apply this formula for all numbers.

Step1:

LCM(645, 965) = 124485

GCD(645, 965) = ( 645 x 965 ) / 124485

= 645 / 965

= 645

Step2:

LCM(5, 447) = 2235

GCD(5, 447) = ( 5 x 447 ) / 2235

= 5 / 447

= 5

Step3:

LCM(1, 543) = 543

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

= 1 / 543

= 1

So, Greatest Common Divisor of 645, 965, 447, 543 is 1
