Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 98/61,70/76,36/160
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 98,70,36
Greatest Common Factor of Numerators i.e. GCF of 98,70,36 is 2 .
LCM of Denominators means LCM of 61,76,160 as per the given fractions.
LCM of 61,76,160 is 185440 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 98,70,36
2 | 98, 70, 36 |
49, 35, 18 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 98
List of positive integer factors of 98 that divides 98 without a remainder.
1,2,7,14,49,98
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 36
List of positive integer factors of 36 that divides 36 without a remainder.
1,2,3,4,6,9,12,18,36
Greatest Common Factor
We found the factors 98,70,36 . The biggest common factor number is the GCF number.
So the greatest common factor 98,70,36 is 2.
Lets's calculate LCM of 61,76,160
2 | 61, 76, 160 |
2 | 61, 38, 80 |
61, 19, 40 |
∴ So the LCM of the given numbers is 2 x 2 x 61 x 19 x 40 = 185440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/185440
Therefore, the GCF of Fractions 98/61,70/76,36/160 is 2/185440
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 61,76,160 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,76,160) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(61,76,160) x common factors =1 x 4 = 4
LCM(61,76,160) = ( 61 × 76 × 160 ) / 4
LCM(61,76,160) = 741760 / 4
LCM(61,76,160) = 185440
