Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 75/68,76/30,139/918
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 75,76,139
Greatest Common Factor of Numerators i.e. GCF of 75,76,139 is 1 .
LCM of Denominators means LCM of 68,30,918 as per the given fractions.
LCM of 68,30,918 is 9180 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 75,76,139
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 75
List of positive integer factors of 75 that divides 75 without a remainder.
1,3,5,15,25,75
Factors of 76
List of positive integer factors of 76 that divides 76 without a remainder.
1,2,4,19,38,76
Factors of 139
List of positive integer factors of 139 that divides 139 without a remainder.
1,139
Greatest Common Factor
We found the factors 75,76,139 . The biggest common factor number is the GCF number.
So the greatest common factor 75,76,139 is 1.
Lets's calculate LCM of 68,30,918
2 | 68, 30, 918 |
3 | 34, 15, 459 |
17 | 34, 5, 153 |
2, 5, 9 |
∴ So the LCM of the given numbers is 2 x 3 x 17 x 2 x 5 x 9 = 9180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9180
Therefore, the GCF of Fractions 75/68,76/30,139/918 is 1/9180
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 68,30,918 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,30,918) = 2
common factors(in case of two or more numbers have common factors) = 102
GCF(68,30,918) x common factors =2 x 102 = 204
LCM(68,30,918) = ( 68 × 30 × 918 ) / 204
LCM(68,30,918) = 1872720 / 204
LCM(68,30,918) = 9180
