Know Least Common Multiple of fractions 56/642, 80/546, 945/354 quickly i.e. 2520 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 56/642, 80/546, 945/354 is 2520.
LCM(56/642, 80/546, 945/354) = 2520
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 56/642,80/546,945/354
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 56,80,945
Least Common Multiple of Numerators i.e. LCM of 56,80,945 is 15120.
GCF of Denominators means GCF of 642,546,354 as per the given fractions.
GCF of 642,546,354 is 6 as it is the largest common factor for these numbers.
Lets's calculate LCM of 56,80,945
2 | 56, 80, 945 |
2 | 28, 40, 945 |
2 | 14, 20, 945 |
5 | 7, 10, 945 |
7 | 7, 2, 189 |
1, 2, 27 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 7 x 1 x 2 x 27 = 15120
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 56,80,945 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(56,80,945) = 1
common factors(in case of two or more numbers have common factors) = 280
GCF(56,80,945) x common factors =1 x 280 = 280
LCM(56,80,945) = ( 56 × 80 × 945 ) / 280
LCM(56,80,945) = 4233600 / 280
LCM(56,80,945) = 15120
Lets's calculate GCF of 642,546,354
2 | 642, 546, 354 |
3 | 321, 273, 177 |
107, 91, 59 |
∴ So the GCF of the given numbers is 2 x 3 = 6
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 15120/6
Therefore the LCM of Fractions 56/642,80/546,945/354 is 2520
