Know Least Common Multiple of fractions 139/224, 7645/434 quickly i.e. 7645/14 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 139/224, 7645/434 is 7645/14.
LCM(139/224, 7645/434) = 7645/14
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 139/224,7645/434
Formula to find LCM of Fractions is
LCM = LCM of Numerators/GCF of Denominators
As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators
In the given fractions LCM of Numerators means LCM of 139,7645
Least Common Multiple of Numerators i.e. LCM of 139,7645 is 7645.
GCF of Denominators means GCF of 224,434 as per the given fractions.
GCF of 224,434 is 14 as it is the largest common factor for these numbers.
Lets's calculate LCM of 139,7645
139 | 139, 7645 |
1, 55 |
∴ So the LCM of the given numbers is 139 x 1 x 55 = 7645
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 139,7645 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(139,7645) = 139
common factors(in case of two or more numbers have common factors) = 1
GCF(139,7645) x common factors =139 x 1 = 139
LCM(139,7645) = ( 139 × 7645 ) / 139
LCM(139,7645) = 1062655 / 139
LCM(139,7645) = 7645
Lets's calculate GCF of 224,434
2 | 224, 434 |
7 | 112, 217 |
16, 31 |
∴ So the GCF of the given numbers is 2 x 7 = 14
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7645/14
Therefore the LCM of Fractions 139/224,7645/434 is 7645/14
