Greatest Common Factor
We found the factors 21,275,318 . The biggest common factor number is the GCF number.
So the greatest common factor 21,275,318 is 1.
Lets's calculate LCM of 50,68,609
2 | 50, 68, 609 |
25, 34, 609 |
∴ So the LCM of the given numbers is 2 x 25 x 34 x 609 = 1035300
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1035300
Therefore, the GCF of Fractions 21/50,275/68,318/609 is 1/1035300
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 50,68,609 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(50,68,609) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(50,68,609) x common factors =1 x 2 = 2
LCM(50,68,609) = ( 50 × 68 × 609 ) / 2
LCM(50,68,609) = 2070600 / 2
LCM(50,68,609) = 1035300
