Given numbers are 815, 605, 875, 873

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

Apply this formula for all numbers.

Step1:

LCM(815, 605) = 98615

GCD(815, 605) = ( 815 x 605 ) / 98615

= 815 / 605

= 815

Step2:

LCM(5, 875) = 875

GCD(5, 875) = ( 5 x 875 ) / 875

= 5 / 875

= 5

Step3:

LCM(5, 873) = 4365

GCD(5, 873) = ( 5 x 873 ) / 4365

= 5 / 873

= 5

So, Greatest Common Divisor of 815, 605, 875, 873 is 1
