Given numbers are 645, 326, 707, 319

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 326 are 2 x 163

Prime factors of 707 are 7 x 101

Prime factors of 319 are 11 x 29

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

Given numbers are 645, 326, 707, 319

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

Apply this formula for all numbers.

Step1:

LCM(645, 326) = 210270

GCD(645, 326) = ( 645 x 326 ) / 210270

= 645 / 326

= 645

Step2:

LCM(1, 707) = 707

GCD(1, 707) = ( 1 x 707 ) / 707

= 1 / 707

= 1

Step3:

LCM(1, 319) = 319

GCD(1, 319) = ( 1 x 319 ) / 319

= 1 / 319

= 1

So, Greatest Common Divisor of 645, 326, 707, 319 is 1
