Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 51/417,30/513
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 51,30
Greatest Common Factor of Numerators i.e. GCF of 51,30 is 3 .
LCM of Denominators means LCM of 417,513 as per the given fractions.
LCM of 417,513 is 71307 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 51,30
3 | 51, 30 |
17, 10 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 51
List of positive integer factors of 51 that divides 51 without a remainder.
1,3,17,51
Factors of 30
List of positive integer factors of 30 that divides 30 without a remainder.
1,2,3,5,6,10,15,30
Greatest Common Factor
We found the factors 51,30 . The biggest common factor number is the GCF number.
So the greatest common factor 51,30 is 3.
Lets's calculate LCM of 417,513
3 | 417, 513 |
139, 171 |
∴ So the LCM of the given numbers is 3 x 139 x 171 = 71307
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/71307
Therefore, the GCF of Fractions 51/417,30/513 is 3/71307
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 417,513 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(417,513) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(417,513) x common factors =3 x 1 = 3
LCM(417,513) = ( 417 × 513 ) / 3
LCM(417,513) = 213921 / 3
LCM(417,513) = 71307
