Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 45/281,1390/4181
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 45,1390
Greatest Common Factor of Numerators i.e. GCF of 45,1390 is 5 .
LCM of Denominators means LCM of 281,4181 as per the given fractions.
LCM of 281,4181 is 1174861 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 45,1390
5 | 45, 1390 |
9, 278 |
∴ So the GCF of the given numbers is 5 = 5

1,2,5,10,139,278,695,1390
Greatest Common Factor
We found the factors 45,1390 . The biggest common factor number is the GCF number.
So the greatest common factor 45,1390 is 5.
Lets's calculate LCM of 281,4181
Given numbers has no common factors except 1. So, there LCM is their product i.e 1174861
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/1174861
Therefore, the GCF of Fractions 45/281,1390/4181 is 5/1174861
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 281,4181 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(281,4181) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(281,4181) x common factors =1 x 1 = 1
LCM(281,4181) = ( 281 × 4181 ) / 1
LCM(281,4181) = 1174861 / 1
LCM(281,4181) = 1174861
