Given numbers are 786, 345, 470, 663

The list of prime factors of all numbers are

Prime factors of 786 are 2 x 3 x 131

Prime factors of 345 are 3 x 5 x 23

Prime factors of 470 are 2 x 5 x 47

Prime factors of 663 are 3 x 13 x 17

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

Given numbers are 786, 345, 470, 663

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

Apply this formula for all numbers.

Step1:

LCM(786, 345) = 90390

GCD(786, 345) = ( 786 x 345 ) / 90390

= 786 / 345

= 786

Step2:

LCM(3, 470) = 1410

GCD(3, 470) = ( 3 x 470 ) / 1410

= 3 / 470

= 3

Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

So, Greatest Common Divisor of 786, 345, 470, 663 is 1
