Given numbers are 840, 345, 457, 926

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 345 are 3 x 5 x 23

Prime factors of 457 are 457

Prime factors of 926 are 2 x 463

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

Given numbers are 840, 345, 457, 926

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

Apply this formula for all numbers.

Step1:

LCM(840, 345) = 19320

GCD(840, 345) = ( 840 x 345 ) / 19320

= 840 / 345

= 840

Step2:

LCM(15, 457) = 6855

GCD(15, 457) = ( 15 x 457 ) / 6855

= 15 / 457

= 15

Step3:

LCM(1, 926) = 926

GCD(1, 926) = ( 1 x 926 ) / 926

= 1 / 926

= 1

So, Greatest Common Divisor of 840, 345, 457, 926 is 1
