Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 166/393,1457/153
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 166,1457
Greatest Common Factor of Numerators i.e. GCF of 166,1457 is 1 .
LCM of Denominators means LCM of 393,153 as per the given fractions.
LCM of 393,153 is 20043 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 166,1457
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 166
List of positive integer factors of 166 that divides 166 without a remainder.
1,2,83,166
Factors of 1457
List of positive integer factors of 1457 that divides 1457 without a remainder.
1,31,47,1457
Greatest Common Factor
We found the factors 166,1457 . The biggest common factor number is the GCF number.
So the greatest common factor 166,1457 is 1.
Lets's calculate LCM of 393,153
3 | 393, 153 |
131, 51 |
∴ So the LCM of the given numbers is 3 x 131 x 51 = 20043
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20043
Therefore, the GCF of Fractions 166/393,1457/153 is 1/20043
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 393,153 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(393,153) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(393,153) x common factors =3 x 1 = 3
LCM(393,153) = ( 393 × 153 ) / 3
LCM(393,153) = 60129 / 3
LCM(393,153) = 20043
