Given numbers are 195, 480, 230, 644

The list of prime factors of all numbers are

Prime factors of 195 are 3 x 5 x 13

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 230 are 2 x 5 x 23

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

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

Given numbers are 195, 480, 230, 644

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

Apply this formula for all numbers.

Step1:

LCM(195, 480) = 6240

GCD(195, 480) = ( 195 x 480 ) / 6240

= 195 / 480

= 195

Step2:

LCM(15, 230) = 690

GCD(15, 230) = ( 15 x 230 ) / 690

= 15 / 230

= 15

Step3:

LCM(5, 644) = 3220

GCD(5, 644) = ( 5 x 644 ) / 3220

= 5 / 644

= 5

So, Greatest Common Divisor of 195, 480, 230, 644 is 1
