Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 248/477,634/665
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 248,634
Greatest Common Factor of Numerators i.e. GCF of 248,634 is 2 .
LCM of Denominators means LCM of 477,665 as per the given fractions.
LCM of 477,665 is 317205 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 248,634
2 | 248, 634 |
124, 317 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 248
List of positive integer factors of 248 that divides 248 without a remainder.
1,2,4,8,31,62,124,248
Factors of 634
List of positive integer factors of 634 that divides 634 without a remainder.
1,2,317,634
Greatest Common Factor
We found the factors 248,634 . The biggest common factor number is the GCF number.
So the greatest common factor 248,634 is 2.
Lets's calculate LCM of 477,665
Given numbers has no common factors except 1. So, there LCM is their product i.e 317205
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/317205
Therefore, the GCF of Fractions 248/477,634/665 is 2/317205
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 477,665 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(477,665) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(477,665) x common factors =1 x 1 = 1
LCM(477,665) = ( 477 × 665 ) / 1
LCM(477,665) = 317205 / 1
LCM(477,665) = 317205
