Given numbers are 753, 396, 390, 305

The list of prime factors of all numbers are

Prime factors of 753 are 3 x 251

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 305 are 5 x 61

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

Given numbers are 753, 396, 390, 305

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

Apply this formula for all numbers.

Step1:

LCM(753, 396) = 99396

GCD(753, 396) = ( 753 x 396 ) / 99396

= 753 / 396

= 753

Step2:

LCM(3, 390) = 390

GCD(3, 390) = ( 3 x 390 ) / 390

= 3 / 390

= 3

Step3:

LCM(3, 305) = 915

GCD(3, 305) = ( 3 x 305 ) / 915

= 3 / 305

= 3

So, Greatest Common Divisor of 753, 396, 390, 305 is 1
