Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 451/720,4961/722
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 451,4961
Greatest Common Factor of Numerators i.e. GCF of 451,4961 is 451 .
LCM of Denominators means LCM of 720,722 as per the given fractions.
LCM of 720,722 is 259920 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 451,4961
11 | 451, 4961 |
41 | 41, 451 |
1, 11 |
∴ So the GCF of the given numbers is 11 x 41 = 451
Factors of 451
List of positive integer factors of 451 that divides 451 without a remainder.
1,11,41,451
Factors of 4961
List of positive integer factors of 4961 that divides 4961 without a remainder.
1,11,41,121,451,4961
Greatest Common Factor
We found the factors 451,4961 . The biggest common factor number is the GCF number.
So the greatest common factor 451,4961 is 451.
Lets's calculate LCM of 720,722
2 | 720, 722 |
360, 361 |
∴ So the LCM of the given numbers is 2 x 360 x 361 = 259920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 451/259920
Therefore, the GCF of Fractions 451/720,4961/722 is 451/259920
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 720,722 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(720,722) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(720,722) x common factors =2 x 1 = 2
LCM(720,722) = ( 720 × 722 ) / 2
LCM(720,722) = 519840 / 2
LCM(720,722) = 259920
