Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 87/830,66/272
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 87,66
Greatest Common Factor of Numerators i.e. GCF of 87,66 is 3 .
LCM of Denominators means LCM of 830,272 as per the given fractions.
LCM of 830,272 is 112880 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 87,66
3 | 87, 66 |
29, 22 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 87
List of positive integer factors of 87 that divides 87 without a remainder.
1,3,29,87
Factors of 66
List of positive integer factors of 66 that divides 66 without a remainder.
1,2,3,6,11,22,33,66
Greatest Common Factor
We found the factors 87,66 . The biggest common factor number is the GCF number.
So the greatest common factor 87,66 is 3.
Lets's calculate LCM of 830,272
2 | 830, 272 |
415, 136 |
∴ So the LCM of the given numbers is 2 x 415 x 136 = 112880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/112880
Therefore, the GCF of Fractions 87/830,66/272 is 3/112880
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 830,272 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(830,272) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(830,272) x common factors =2 x 1 = 2
LCM(830,272) = ( 830 × 272 ) / 2
LCM(830,272) = 225760 / 2
LCM(830,272) = 112880
