Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 49/938,84/2141
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 49,84
Greatest Common Factor of Numerators i.e. GCF of 49,84 is 7 .
LCM of Denominators means LCM of 938,2141 as per the given fractions.
LCM of 938,2141 is 2008258 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 49,84
7 | 49, 84 |
7, 12 |
∴ So the GCF of the given numbers is 7 = 7
Factors of 49
List of positive integer factors of 49 that divides 49 without a remainder.
1,7,49
Factors of 84
List of positive integer factors of 84 that divides 84 without a remainder.
1,2,3,4,6,7,12,14,21,28,42,84
Greatest Common Factor
We found the factors 49,84 . The biggest common factor number is the GCF number.
So the greatest common factor 49,84 is 7.
Lets's calculate LCM of 938,2141
Given numbers has no common factors except 1. So, there LCM is their product i.e 2008258
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/2008258
Therefore, the GCF of Fractions 49/938,84/2141 is 7/2008258
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 938,2141 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(938,2141) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(938,2141) x common factors =1 x 1 = 1
LCM(938,2141) = ( 938 × 2141 ) / 1
LCM(938,2141) = 2008258 / 1
LCM(938,2141) = 2008258
