Given numbers are 645, 540, 758, 204

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 758 are 2 x 379

Prime factors of 204 are 2 x 2 x 3 x 17

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

Given numbers are 645, 540, 758, 204

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

Apply this formula for all numbers.

Step1:

LCM(645, 540) = 23220

GCD(645, 540) = ( 645 x 540 ) / 23220

= 645 / 540

= 645

Step2:

LCM(15, 758) = 11370

GCD(15, 758) = ( 15 x 758 ) / 11370

= 15 / 758

= 15

Step3:

LCM(1, 204) = 204

GCD(1, 204) = ( 1 x 204 ) / 204

= 1 / 204

= 1

So, Greatest Common Divisor of 645, 540, 758, 204 is 1
