Given numbers are 396, 700, 289, 645

The list of prime factors of all numbers are

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 700 are 2 x 2 x 5 x 5 x 7

Prime factors of 289 are 17 x 17

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 396, 700, 289, 645

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

Apply this formula for all numbers.

Step1:

LCM(396, 700) = 69300

GCD(396, 700) = ( 396 x 700 ) / 69300

= 396 / 700

= 396

Step2:

LCM(4, 289) = 1156

GCD(4, 289) = ( 4 x 289 ) / 1156

= 4 / 289

= 4

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 396, 700, 289, 645 is 1
