Given numbers are 521, 323, 420, 878

The list of prime factors of all numbers are

Prime factors of 521 are 521

Prime factors of 323 are 17 x 19

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 878 are 2 x 439

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

Given numbers are 521, 323, 420, 878

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

Apply this formula for all numbers.

Step1:

LCM(521, 323) = 168283

GCD(521, 323) = ( 521 x 323 ) / 168283

= 521 / 323

= 521

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

So, Greatest Common Divisor of 521, 323, 420, 878 is 1
