Given numbers are 855, 343, 487

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

Apply this formula for all numbers.

Step1:

LCM(855, 343) = 293265

GCD(855, 343) = ( 855 x 343 ) / 293265

= 855 / 343

= 855

Step2:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

So, Greatest Common Divisor of 855, 343, 487 is 1
