Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 74/108,487/310
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 74,487
Greatest Common Factor of Numerators i.e. GCF of 74,487 is 1 .
LCM of Denominators means LCM of 108,310 as per the given fractions.
LCM of 108,310 is 16740 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 74,487
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 74
List of positive integer factors of 74 that divides 74 without a remainder.
1,2,37,74
Factors of 487
List of positive integer factors of 487 that divides 487 without a remainder.
1,487
Greatest Common Factor
We found the factors 74,487 . The biggest common factor number is the GCF number.
So the greatest common factor 74,487 is 1.
Lets's calculate LCM of 108,310
2 | 108, 310 |
54, 155 |
∴ So the LCM of the given numbers is 2 x 54 x 155 = 16740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/16740
Therefore, the GCF of Fractions 74/108,487/310 is 1/16740
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 108,310 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(108,310) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(108,310) x common factors =2 x 1 = 2
LCM(108,310) = ( 108 × 310 ) / 2
LCM(108,310) = 33480 / 2
LCM(108,310) = 16740
