Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 65/558,55/4120
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 65,55
Greatest Common Factor of Numerators i.e. GCF of 65,55 is 5 .
LCM of Denominators means LCM of 558,4120 as per the given fractions.
LCM of 558,4120 is 1149480 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 65,55
5 | 65, 55 |
13, 11 |
∴ So the GCF of the given numbers is 5 = 5
Factors of 65
List of positive integer factors of 65 that divides 65 without a remainder.
1,5,13,65
Factors of 55
List of positive integer factors of 55 that divides 55 without a remainder.
1,5,11,55
Greatest Common Factor
We found the factors 65,55 . The biggest common factor number is the GCF number.
So the greatest common factor 65,55 is 5.
Lets's calculate LCM of 558,4120
2 | 558, 4120 |
279, 2060 |
∴ So the LCM of the given numbers is 2 x 279 x 2060 = 1149480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/1149480
Therefore, the GCF of Fractions 65/558,55/4120 is 5/1149480
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 558,4120 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(558,4120) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(558,4120) x common factors =2 x 1 = 2
LCM(558,4120) = ( 558 × 4120 ) / 2
LCM(558,4120) = 2298960 / 2
LCM(558,4120) = 1149480
