Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 870/91,3408/443
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 870,3408
Greatest Common Factor of Numerators i.e. GCF of 870,3408 is 6 .
LCM of Denominators means LCM of 91,443 as per the given fractions.
LCM of 91,443 is 40313 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 870,3408
2 | 870, 3408 |
3 | 435, 1704 |
145, 568 |
∴ So the GCF of the given numbers is 2 x 3 = 6

Greatest Common Factor
We found the factors 870,3408 . The biggest common factor number is the GCF number.
So the greatest common factor 870,3408 is 6.
Lets's calculate LCM of 91,443
Given numbers has no common factors except 1. So, there LCM is their product i.e 40313
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/40313
Therefore, the GCF of Fractions 870/91,3408/443 is 6/40313
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 91,443 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,443) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(91,443) x common factors =1 x 1 = 1
LCM(91,443) = ( 91 × 443 ) / 1
LCM(91,443) = 40313 / 1
LCM(91,443) = 40313
