Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 71/851,15/3887
To find the GCF of fractions, we have to find the GCF of numerator numbers and LCM of denominator numbers. Its formula is given by
GCF of Fraction = Greatest Common Factor of Numerator/Least Common Multiple of Denominators
In the fractions 71/851,15/3887, numerators are 71,15
Denominators are 851,3887
The GCF of 71,15 is 1 .
LCM of 851,3887 is 143819.
The greatest common factor of 71/851,15/3887 = [GCF of 71,15]/[LCM of 851,3887]= 1/143819
Therefore, the GCF of 71/851,15/3887 is 1/143819.
To find the highest common factor of 71,15, we have to find the factors of both numbers and list the highest common factor.
The factors of 71 are 1, 71
The factors of 15 are 1, 3, 5, 15
The HCF of 71,15 is 1.
Lets's calculate GCF of 71,15
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 851,3887
23 | 851, 3887 |
37, 169 |
∴ So the LCM of the given numbers is 23 x 37 x 169 = 143819
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/143819
Therefore, the GCF of Fractions 71/851,15/3887 is 1/143819
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 851,3887 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(851,3887) = 23
common factors(in case of two or more numbers have common factors) = 1
GCF(851,3887) x common factors =23 x 1 = 23
LCM(851,3887) = ( 851 × 3887 ) / 23
LCM(851,3887) = 3307837 / 23
LCM(851,3887) = 143819
