Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 46/50,90/21,748/64
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 46,90,748
Greatest Common Factor of Numerators i.e. GCF of 46,90,748 is 2 .
LCM of Denominators means LCM of 50,21,64 as per the given fractions.
LCM of 50,21,64 is 33600 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 46,90,748
2 | 46, 90, 748 |
23, 45, 374 |
∴ So the GCF of the given numbers is 2 = 2

List of positive integer factors of 46 that divides 46 without a remainder.
1,2,23,46
Factors of 90
List of positive integer factors of 90 that divides 90 without a remainder.
1,2,3,5,6,9,10,15,18,30,45,90
Factors of 748
List of positive integer factors of 748 that divides 748 without a remainder.
1,2,4,11,17,22,34,44,68,187,374,748
Greatest Common Factor
We found the factors 46,90,748 . The biggest common factor number is the GCF number.
So the greatest common factor 46,90,748 is 2.
Lets's calculate LCM of 50,21,64
2 | 50, 21, 64 |
25, 21, 32 |
∴ So the LCM of the given numbers is 2 x 25 x 21 x 32 = 33600
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/33600
Therefore, the GCF of Fractions 46/50,90/21,748/64 is 2/33600
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 50,21,64 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(50,21,64) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(50,21,64) x common factors =1 x 2 = 2
LCM(50,21,64) = ( 50 × 21 × 64 ) / 2
LCM(50,21,64) = 67200 / 2
LCM(50,21,64) = 33600
