Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 64/28,77/50,81/450
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 64,77,81
Greatest Common Factor of Numerators i.e. GCF of 64,77,81 is 1 .
LCM of Denominators means LCM of 28,50,450 as per the given fractions.
LCM of 28,50,450 is 6300 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 64,77,81
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 64
List of positive integer factors of 64 that divides 64 without a remainder.
1,2,4,8,16,32,64
Factors of 77
List of positive integer factors of 77 that divides 77 without a remainder.
1,7,11,77
Factors of 81
List of positive integer factors of 81 that divides 81 without a remainder.
1,3,9,27,81
Greatest Common Factor
We found the factors 64,77,81 . The biggest common factor number is the GCF number.
So the greatest common factor 64,77,81 is 1.
Lets's calculate LCM of 28,50,450
2 | 28, 50, 450 |
5 | 14, 25, 225 |
5 | 14, 5, 45 |
14, 1, 9 |
∴ So the LCM of the given numbers is 2 x 5 x 5 x 14 x 1 x 9 = 6300
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6300
Therefore, the GCF of Fractions 64/28,77/50,81/450 is 1/6300
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 28,50,450 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,50,450) = 2
common factors(in case of two or more numbers have common factors) = 50
GCF(28,50,450) x common factors =2 x 50 = 100
LCM(28,50,450) = ( 28 × 50 × 450 ) / 100
LCM(28,50,450) = 630000 / 100
LCM(28,50,450) = 6300
