Know Least Common Multiple of fractions 61/98, 55/78, 690/624 quickly i.e. 231495 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 61/98, 55/78, 690/624 is 231495.
LCM(61/98, 55/78, 690/624) = 231495
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 61/98,55/78,690/624
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 61,55,690
Least Common Multiple of Numerators i.e. LCM of 61,55,690 is 462990.
GCF of Denominators means GCF of 98,78,624 as per the given fractions.
GCF of 98,78,624 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 61,55,690
5 | 61, 55, 690 |
61, 11, 138 |
∴ So the LCM of the given numbers is 5 x 61 x 11 x 138 = 462990
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 61,55,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,55,690) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(61,55,690) x common factors =1 x 5 = 5
LCM(61,55,690) = ( 61 × 55 × 690 ) / 5
LCM(61,55,690) = 2314950 / 5
LCM(61,55,690) = 462990
Lets's calculate GCF of 98,78,624
2 | 98, 78, 624 |
49, 39, 312 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 462990/2
Therefore the LCM of Fractions 61/98,55/78,690/624 is 231495
