Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 4/18,232/32,297/64
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 4,232,297
Greatest Common Factor of Numerators i.e. GCF of 4,232,297 is 1 .
LCM of Denominators means LCM of 18,32,64 as per the given fractions.
LCM of 18,32,64 is 576 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 4,232,297
∴ So GCF of numbers is 1 because of no common factors present between them.

1,3,9,11,27,33,99,297
Greatest Common Factor
We found the factors 4,232,297 . The biggest common factor number is the GCF number.
So the greatest common factor 4,232,297 is 1.
Lets's calculate LCM of 18,32,64
2 | 18, 32, 64 |
2 | 9, 16, 32 |
2 | 9, 8, 16 |
2 | 9, 4, 8 |
2 | 9, 2, 4 |
9, 1, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 9 x 1 x 2 = 576
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/576
Therefore, the GCF of Fractions 4/18,232/32,297/64 is 1/576
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 18,32,64 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,32,64) = 2
common factors(in case of two or more numbers have common factors) = 32
GCF(18,32,64) x common factors =2 x 32 = 64
LCM(18,32,64) = ( 18 × 32 × 64 ) / 64
LCM(18,32,64) = 36864 / 64
LCM(18,32,64) = 576
