Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 65/408,164/507
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 65,164
Greatest Common Factor of Numerators i.e. GCF of 65,164 is 1 .
LCM of Denominators means LCM of 408,507 as per the given fractions.
LCM of 408,507 is 68952 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 65,164
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 65
List of positive integer factors of 65 that divides 65 without a remainder.
1,5,13,65
Factors of 164
List of positive integer factors of 164 that divides 164 without a remainder.
1,2,4,41,82,164
Greatest Common Factor
We found the factors 65,164 . The biggest common factor number is the GCF number.
So the greatest common factor 65,164 is 1.
Lets's calculate LCM of 408,507
3 | 408, 507 |
136, 169 |
∴ So the LCM of the given numbers is 3 x 136 x 169 = 68952
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/68952
Therefore, the GCF of Fractions 65/408,164/507 is 1/68952
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 408,507 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(408,507) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(408,507) x common factors =3 x 1 = 3
LCM(408,507) = ( 408 × 507 ) / 3
LCM(408,507) = 206856 / 3
LCM(408,507) = 68952
