Given numbers are 345, 788, 681, 812

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 788 are 2 x 2 x 197

Prime factors of 681 are 3 x 227

Prime factors of 812 are 2 x 2 x 7 x 29

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

Given numbers are 345, 788, 681, 812

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

Apply this formula for all numbers.

Step1:

LCM(345, 788) = 271860

GCD(345, 788) = ( 345 x 788 ) / 271860

= 345 / 788

= 345

Step2:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

Step3:

LCM(1, 812) = 812

GCD(1, 812) = ( 1 x 812 ) / 812

= 1 / 812

= 1

So, Greatest Common Divisor of 345, 788, 681, 812 is 1
