Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 66/882,77/490
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 66,77
Greatest Common Factor of Numerators i.e. GCF of 66,77 is 11 .
LCM of Denominators means LCM of 882,490 as per the given fractions.
LCM of 882,490 is 4410 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 66,77
11 | 66, 77 |
6, 7 |
∴ So the GCF of the given numbers is 11 = 11
Factors of 66
List of positive integer factors of 66 that divides 66 without a remainder.
1,2,3,6,11,22,33,66
Factors of 77
List of positive integer factors of 77 that divides 77 without a remainder.
1,7,11,77
Greatest Common Factor
We found the factors 66,77 . The biggest common factor number is the GCF number.
So the greatest common factor 66,77 is 11.
Lets's calculate LCM of 882,490
2 | 882, 490 |
7 | 441, 245 |
7 | 63, 35 |
9, 5 |
∴ So the LCM of the given numbers is 2 x 7 x 7 x 9 x 5 = 4410
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/4410
Therefore, the GCF of Fractions 66/882,77/490 is 11/4410
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 882,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(882,490) = 98
common factors(in case of two or more numbers have common factors) = 1
GCF(882,490) x common factors =98 x 1 = 98
LCM(882,490) = ( 882 × 490 ) / 98
LCM(882,490) = 432180 / 98
LCM(882,490) = 4410
