Know Least Common Multiple of fractions 85/10, 70/80, 140/412 quickly i.e. 1190 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 85/10, 70/80, 140/412 is 1190.
LCM(85/10, 70/80, 140/412) = 1190
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 85/10,70/80,140/412
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 85,70,140
Least Common Multiple of Numerators i.e. LCM of 85,70,140 is 2380.
GCF of Denominators means GCF of 10,80,412 as per the given fractions.
GCF of 10,80,412 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 85,70,140
2 | 85, 70, 140 |
5 | 85, 35, 70 |
7 | 17, 7, 14 |
17, 1, 2 |
∴ So the LCM of the given numbers is 2 x 5 x 7 x 17 x 1 x 2 = 2380
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 85,70,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,70,140) = 5
common factors(in case of two or more numbers have common factors) = 70
GCF(85,70,140) x common factors =5 x 70 = 350
LCM(85,70,140) = ( 85 × 70 × 140 ) / 350
LCM(85,70,140) = 833000 / 350
LCM(85,70,140) = 2380
Lets's calculate GCF of 10,80,412
2 | 10, 80, 412 |
5, 40, 206 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2380/2
Therefore the LCM of Fractions 85/10,70/80,140/412 is 1190
