Given numbers are 780, 768, 408, 229

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 229 are 229

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

Given numbers are 780, 768, 408, 229

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

Apply this formula for all numbers.

Step1:

LCM(780, 768) = 49920

GCD(780, 768) = ( 780 x 768 ) / 49920

= 780 / 768

= 780

Step2:

LCM(12, 408) = 408

GCD(12, 408) = ( 12 x 408 ) / 408

= 12 / 408

= 12

Step3:

LCM(12, 229) = 2748

GCD(12, 229) = ( 12 x 229 ) / 2748

= 12 / 229

= 12

So, Greatest Common Divisor of 780, 768, 408, 229 is 1
