Know Least Common Multiple of fractions 680/90, 117/1490 quickly i.e. 7956 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 680/90, 117/1490 is 7956.
LCM(680/90, 117/1490) = 7956
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 680/90,117/1490
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 680,117
Least Common Multiple of Numerators i.e. LCM of 680,117 is 79560.
GCF of Denominators means GCF of 90,1490 as per the given fractions.
GCF of 90,1490 is 10 as it is the largest common factor for these numbers.
Lets's calculate LCM of 680,117
Given numbers has no common factors except 1. So, there LCM is their product i.e 79560
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 680,117 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(680,117) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(680,117) x common factors =1 x 1 = 1
LCM(680,117) = ( 680 × 117 ) / 1
LCM(680,117) = 79560 / 1
LCM(680,117) = 79560
Lets's calculate GCF of 90,1490
2 | 90, 1490 |
5 | 45, 745 |
9, 149 |
∴ So the GCF of the given numbers is 2 x 5 = 10
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 79560/10
Therefore the LCM of Fractions 680/90,117/1490 is 7956
