Greatest Common Factor
We found the factors 18,890,942 . The biggest common factor number is the GCF number.
So the greatest common factor 18,890,942 is 2.
Lets's calculate LCM of 35,53,790
5 | 35, 53, 790 |
7, 53, 158 |
∴ So the LCM of the given numbers is 5 x 7 x 53 x 158 = 293090
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/293090
Therefore, the GCF of Fractions 18/35,890/53,942/790 is 2/293090
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 35,53,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(35,53,790) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(35,53,790) x common factors =1 x 5 = 5
LCM(35,53,790) = ( 35 × 53 × 790 ) / 5
LCM(35,53,790) = 1465450 / 5
LCM(35,53,790) = 293090
