Given numbers are 345, 856, 823, 540

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 823 are 823

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

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

Given numbers are 345, 856, 823, 540

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

Apply this formula for all numbers.

Step1:

LCM(345, 856) = 295320

GCD(345, 856) = ( 345 x 856 ) / 295320

= 345 / 856

= 345

Step2:

LCM(1, 823) = 823

GCD(1, 823) = ( 1 x 823 ) / 823

= 1 / 823

= 1

Step3:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

So, Greatest Common Divisor of 345, 856, 823, 540 is 1
