Know Least Common Multiple of fractions 420/614, 690/123, 126/692 quickly i.e. 28980 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 420/614, 690/123, 126/692 is 28980.
LCM(420/614, 690/123, 126/692) = 28980
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 420/614,690/123,126/692
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 420,690,126
Least Common Multiple of Numerators i.e. LCM of 420,690,126 is 28980.
GCF of Denominators means GCF of 614,123,692 as per the given fractions.
GCF of 614,123,692 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 420,690,126
2 | 420, 690, 126 |
3 | 210, 345, 63 |
5 | 70, 115, 21 |
7 | 14, 23, 21 |
2, 23, 3 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 2 x 23 x 3 = 28980
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 420,690,126 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,690,126) = 6
common factors(in case of two or more numbers have common factors) = 210
GCF(420,690,126) x common factors =6 x 210 = 1260
LCM(420,690,126) = ( 420 × 690 × 126 ) / 1260
LCM(420,690,126) = 36514800 / 1260
LCM(420,690,126) = 28980
Lets's calculate GCF of 614,123,692
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 28980/1
Therefore the LCM of Fractions 420/614,690/123,126/692 is 28980
