Given numbers are 788, 221, 390, 468

The list of prime factors of all numbers are

Prime factors of 788 are 2 x 2 x 197

Prime factors of 221 are 13 x 17

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

Prime factors of 468 are 2 x 2 x 3 x 3 x 13

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

Given numbers are 788, 221, 390, 468

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

Apply this formula for all numbers.

Step1:

LCM(788, 221) = 174148

GCD(788, 221) = ( 788 x 221 ) / 174148

= 788 / 221

= 788

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 468) = 468

GCD(1, 468) = ( 1 x 468 ) / 468

= 1 / 468

= 1

So, Greatest Common Divisor of 788, 221, 390, 468 is 1
