Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 21/65,92/14,70/32,44/33
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 21,92,70,44
Greatest Common Factor of Numerators i.e. GCF of 21,92,70,44 is 1 .
LCM of Denominators means LCM of 65,14,32,33 as per the given fractions.
LCM of 65,14,32,33 is 480480 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 21,92,70,44
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 21
List of positive integer factors of 21 that divides 21 without a remainder.
1,3,7,21
Factors of 92
List of positive integer factors of 92 that divides 92 without a remainder.
1,2,4,23,46,92
Factors of 70
List of positive integer factors of 70 that divides 70 without a remainder.
1,2,5,7,10,14,35,70
Factors of 44
List of positive integer factors of 44 that divides 44 without a remainder.
1,2,4,11,22,44
Greatest Common Factor
We found the factors 21,92,70,44 . The biggest common factor number is the GCF number.
So the greatest common factor 21,92,70,44 is 1.
Lets's calculate LCM of 65,14,32,33
2 | 65, 14, 32, 33 |
65, 7, 16, 33 |
∴ So the LCM of the given numbers is 2 x 65 x 7 x 16 x 33 = 480480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/480480
Therefore, the GCF of Fractions 21/65,92/14,70/32,44/33 is 1/480480
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 65,14,32,33 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,14,32,33) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(65,14,32,33) x common factors =1 x 2 = 2
LCM(65,14,32,33) = ( 65 × 14 × 32 × 33 ) / 2
LCM(65,14,32,33) = 960960 / 2
LCM(65,14,32,33) = 480480
