Given numbers are 345, 640, 649, 303

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 649 are 11 x 59

Prime factors of 303 are 3 x 101

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

Given numbers are 345, 640, 649, 303

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

Apply this formula for all numbers.

Step1:

LCM(345, 640) = 44160

GCD(345, 640) = ( 345 x 640 ) / 44160

= 345 / 640

= 345

Step2:

LCM(5, 649) = 3245

GCD(5, 649) = ( 5 x 649 ) / 3245

= 5 / 649

= 5

Step3:

LCM(1, 303) = 303

GCD(1, 303) = ( 1 x 303 ) / 303

= 1 / 303

= 1

So, Greatest Common Divisor of 345, 640, 649, 303 is 1
