Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 85/471,318/381
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 85,318
Greatest Common Factor of Numerators i.e. GCF of 85,318 is 1 .
LCM of Denominators means LCM of 471,381 as per the given fractions.
LCM of 471,381 is 59817 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 85,318
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 85
List of positive integer factors of 85 that divides 85 without a remainder.
1,5,17,85
Factors of 318
List of positive integer factors of 318 that divides 318 without a remainder.
1,2,3,6,53,106,159,318
Greatest Common Factor
We found the factors 85,318 . The biggest common factor number is the GCF number.
So the greatest common factor 85,318 is 1.
Lets's calculate LCM of 471,381
3 | 471, 381 |
157, 127 |
∴ So the LCM of the given numbers is 3 x 157 x 127 = 59817
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/59817
Therefore, the GCF of Fractions 85/471,318/381 is 1/59817
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 471,381 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(471,381) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(471,381) x common factors =3 x 1 = 3
LCM(471,381) = ( 471 × 381 ) / 3
LCM(471,381) = 179451 / 3
LCM(471,381) = 59817
