GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(873, 687) = 199917
GCD(873, 687) = ( 873 x 687 ) / 199917
= 873 / 687
= 873
Step2:
LCM(3, 345) = 345
GCD(3, 345) = ( 3 x 345 ) / 345
= 3 / 345
= 3
Step3:
LCM(3, 555) = 555
GCD(3, 555) = ( 3 x 555 ) / 555
= 3 / 555
= 3
So, Greatest Common Divisor of 873, 687, 345, 555 is 3
