Given numbers are 396, 645, 360, 139

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 645 are 3 x 5 x 43

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 139 are 139

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

Given numbers are 396, 645, 360, 139

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

Apply this formula for all numbers.

Step1:

LCM(396, 645) = 85140

GCD(396, 645) = ( 396 x 645 ) / 85140

= 396 / 645

= 396

Step2:

LCM(3, 360) = 360

GCD(3, 360) = ( 3 x 360 ) / 360

= 3 / 360

= 3

Step3:

LCM(3, 139) = 417

GCD(3, 139) = ( 3 x 139 ) / 417

= 3 / 139

= 3

So, Greatest Common Divisor of 396, 645, 360, 139 is 1
