Given numbers are 645, 520, 714, 192

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 714 are 2 x 3 x 7 x 17

Prime factors of 192 are 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 645, 520, 714, 192

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

Apply this formula for all numbers.

Step1:

LCM(645, 520) = 67080

GCD(645, 520) = ( 645 x 520 ) / 67080

= 645 / 520

= 645

Step2:

LCM(5, 714) = 3570

GCD(5, 714) = ( 5 x 714 ) / 3570

= 5 / 714

= 5

Step3:

LCM(1, 192) = 192

GCD(1, 192) = ( 1 x 192 ) / 192

= 1 / 192

= 1

So, Greatest Common Divisor of 645, 520, 714, 192 is 1
