Given numbers are 439, 878, 805, 560

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

Apply this formula for all numbers.

Step1:

LCM(439, 878) = 878

GCD(439, 878) = ( 439 x 878 ) / 878

= 439 / 878

= 439

Step2:

LCM(439, 805) = 353395

GCD(439, 805) = ( 439 x 805 ) / 353395

= 439 / 805

= 439

Step3:

LCM(1, 560) = 560

GCD(1, 560) = ( 1 x 560 ) / 560

= 1 / 560

= 1

So, Greatest Common Divisor of 439, 878, 805, 560 is 1
