Know Least Common Multiple of fractions 972/847, 6990/630 quickly i.e. 1132380/7 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 972/847, 6990/630 is 1132380/7.
LCM(972/847, 6990/630) = 1132380/7
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 972/847,6990/630
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 972,6990
Least Common Multiple of Numerators i.e. LCM of 972,6990 is 1132380.
GCF of Denominators means GCF of 847,630 as per the given fractions.
GCF of 847,630 is 7 as it is the largest common factor for these numbers.
Lets's calculate LCM of 972,6990
2 | 972, 6990 |
3 | 486, 3495 |
162, 1165 |
∴ So the LCM of the given numbers is 2 x 3 x 162 x 1165 = 1132380
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 972,6990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(972,6990) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(972,6990) x common factors =6 x 1 = 6
LCM(972,6990) = ( 972 × 6990 ) / 6
LCM(972,6990) = 6794280 / 6
LCM(972,6990) = 1132380
Lets's calculate GCF of 847,630
7 | 847, 630 |
121, 90 |
∴ So the GCF of the given numbers is 7 = 7
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1132380/7
Therefore the LCM of Fractions 972/847,6990/630 is 1132380/7
