Given numbers are 345, 340, 439, 822

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 439 are 439

Prime factors of 822 are 2 x 3 x 137

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

Given numbers are 345, 340, 439, 822

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

Apply this formula for all numbers.

Step1:

LCM(345, 340) = 23460

GCD(345, 340) = ( 345 x 340 ) / 23460

= 345 / 340

= 345

Step2:

LCM(5, 439) = 2195

GCD(5, 439) = ( 5 x 439 ) / 2195

= 5 / 439

= 5

Step3:

LCM(1, 822) = 822

GCD(1, 822) = ( 1 x 822 ) / 822

= 1 / 822

= 1

So, Greatest Common Divisor of 345, 340, 439, 822 is 1
