Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 91/518,31/3778
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 91/518,31/3778, numerators are 91,31
Denominators are 518,3778
The GCF of 91,31 is 1 .
LCM of 518,3778 is 978502.
The greatest common factor of 91/518,31/3778 = [GCF of 91,31]/[LCM of 518,3778]= 1/978502
Therefore, the GCF of 91/518,31/3778 is 1/978502.
To find the highest common factor of 91,31, we have to find the factors of both numbers and list the highest common factor.
The factors of 91 are 1, 7, 13, 91
The factors of 31 are 1, 31
The HCF of 91,31 is 1.
Lets's calculate GCF of 91,31
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 518,3778
2 | 518, 3778 |
259, 1889 |
∴ So the LCM of the given numbers is 2 x 259 x 1889 = 978502
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/978502
Therefore, the GCF of Fractions 91/518,31/3778 is 1/978502
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 518,3778 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(518,3778) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(518,3778) x common factors =2 x 1 = 2
LCM(518,3778) = ( 518 × 3778 ) / 2
LCM(518,3778) = 1957004 / 2
LCM(518,3778) = 978502
