Greatest Common Factor
We found the factors 99,642,972 . The biggest common factor number is the GCF number.
So the greatest common factor 99,642,972 is 3.
Lets's calculate LCM of 689,992,543
Given numbers has no common factors except 1. So, there LCM is their product i.e 371133984
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/371133984
Therefore, the GCF of Fractions 99/689,642/992,972/543 is 3/371133984
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 689,992,543 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(689,992,543) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(689,992,543) x common factors =1 x 1 = 1
LCM(689,992,543) = ( 689 × 992 × 543 ) / 1
LCM(689,992,543) = 371133984 / 1
LCM(689,992,543) = 371133984
