Given numbers are 195, 646, 409, 624

The list of prime factors of all numbers are

Prime factors of 195 are 3 x 5 x 13

Prime factors of 646 are 2 x 17 x 19

Prime factors of 409 are 409

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

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

Given numbers are 195, 646, 409, 624

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

Apply this formula for all numbers.

Step1:

LCM(195, 646) = 125970

GCD(195, 646) = ( 195 x 646 ) / 125970

= 195 / 646

= 195

Step2:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

Step3:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

So, Greatest Common Divisor of 195, 646, 409, 624 is 1
