Know Least Common Multiple of fractions 2176/640, 1703/778 quickly i.e. 1852864 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 2176/640, 1703/778 is 1852864.
LCM(2176/640, 1703/778) = 1852864
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 2176/640,1703/778
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 2176,1703
Least Common Multiple of Numerators i.e. LCM of 2176,1703 is 3705728.
GCF of Denominators means GCF of 640,778 as per the given fractions.
GCF of 640,778 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 2176,1703
Given numbers has no common factors except 1. So, there LCM is their product i.e 3705728
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 2176,1703 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(2176,1703) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(2176,1703) x common factors =1 x 1 = 1
LCM(2176,1703) = ( 2176 × 1703 ) / 1
LCM(2176,1703) = 3705728 / 1
LCM(2176,1703) = 3705728
Lets's calculate GCF of 640,778
2 | 640, 778 |
320, 389 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3705728/2
Therefore the LCM of Fractions 2176/640,1703/778 is 1852864
