Given numbers are 328, 360, 644, 139

The list of prime factors of all numbers are

Prime factors of 328 are 2 x 2 x 2 x 41

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

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 139 are 139

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

Given numbers are 328, 360, 644, 139

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

Apply this formula for all numbers.

Step1:

LCM(328, 360) = 14760

GCD(328, 360) = ( 328 x 360 ) / 14760

= 328 / 360

= 328

Step2:

LCM(8, 644) = 1288

GCD(8, 644) = ( 8 x 644 ) / 1288

= 8 / 644

= 8

Step3:

LCM(4, 139) = 556

GCD(4, 139) = ( 4 x 139 ) / 556

= 4 / 139

= 4

So, Greatest Common Divisor of 328, 360, 644, 139 is 1
