Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 221/473,356/836
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 221,356
Greatest Common Factor of Numerators i.e. GCF of 221,356 is 1 .
LCM of Denominators means LCM of 473,836 as per the given fractions.
LCM of 473,836 is 35948 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 221,356
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 221
List of positive integer factors of 221 that divides 221 without a remainder.
1,13,17,221
Factors of 356
List of positive integer factors of 356 that divides 356 without a remainder.
1,2,4,89,178,356
Greatest Common Factor
We found the factors 221,356 . The biggest common factor number is the GCF number.
So the greatest common factor 221,356 is 1.
Lets's calculate LCM of 473,836
11 | 473, 836 |
43, 76 |
∴ So the LCM of the given numbers is 11 x 43 x 76 = 35948
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/35948
Therefore, the GCF of Fractions 221/473,356/836 is 1/35948
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 473,836 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(473,836) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(473,836) x common factors =11 x 1 = 11
LCM(473,836) = ( 473 × 836 ) / 11
LCM(473,836) = 395428 / 11
LCM(473,836) = 35948
