Given numbers are 819, 340, 354, 457

The list of prime factors of all numbers are

Prime factors of 819 are 3 x 3 x 7 x 13

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

Prime factors of 354 are 2 x 3 x 59

Prime factors of 457 are 457

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

Given numbers are 819, 340, 354, 457

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

Apply this formula for all numbers.

Step1:

LCM(819, 340) = 278460

GCD(819, 340) = ( 819 x 340 ) / 278460

= 819 / 340

= 819

Step2:

LCM(1, 354) = 354

GCD(1, 354) = ( 1 x 354 ) / 354

= 1 / 354

= 1

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 819, 340, 354, 457 is 1
