Given numbers are 646, 153, 293, 518

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 153 are 3 x 3 x 17

Prime factors of 293 are 293

Prime factors of 518 are 2 x 7 x 37

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

Given numbers are 646, 153, 293, 518

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

Apply this formula for all numbers.

Step1:

LCM(646, 153) = 5814

GCD(646, 153) = ( 646 x 153 ) / 5814

= 646 / 153

= 646

Step2:

LCM(17, 293) = 4981

GCD(17, 293) = ( 17 x 293 ) / 4981

= 17 / 293

= 17

Step3:

LCM(1, 518) = 518

GCD(1, 518) = ( 1 x 518 ) / 518

= 1 / 518

= 1

So, Greatest Common Divisor of 646, 153, 293, 518 is 1
