Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 80/72,36/41,117/782
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 80,36,117
Greatest Common Factor of Numerators i.e. GCF of 80,36,117 is 1 .
LCM of Denominators means LCM of 72,41,782 as per the given fractions.
LCM of 72,41,782 is 1154232 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 80,36,117
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 80
List of positive integer factors of 80 that divides 80 without a remainder.
1,2,4,5,8,10,16,20,40,80
Factors of 36
List of positive integer factors of 36 that divides 36 without a remainder.
1,2,3,4,6,9,12,18,36
Factors of 117
List of positive integer factors of 117 that divides 117 without a remainder.
1,3,9,13,39,117
Greatest Common Factor
We found the factors 80,36,117 . The biggest common factor number is the GCF number.
So the greatest common factor 80,36,117 is 1.
Lets's calculate LCM of 72,41,782
2 | 72, 41, 782 |
36, 41, 391 |
∴ So the LCM of the given numbers is 2 x 36 x 41 x 391 = 1154232
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1154232
Therefore, the GCF of Fractions 80/72,36/41,117/782 is 1/1154232
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 72,41,782 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,41,782) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(72,41,782) x common factors =1 x 2 = 2
LCM(72,41,782) = ( 72 × 41 × 782 ) / 2
LCM(72,41,782) = 2308464 / 2
LCM(72,41,782) = 1154232
