Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 70/558,85/4356
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 70,85
Greatest Common Factor of Numerators i.e. GCF of 70,85 is 5 .
LCM of Denominators means LCM of 558,4356 as per the given fractions.
LCM of 558,4356 is 135036 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 70,85
5 | 70, 85 |
14, 17 |
∴ So the GCF of the given numbers is 5 = 5
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 85
List of positive integer factors of 85 that divides 85 without a remainder.
1,5,17,85
Greatest Common Factor
We found the factors 70,85 . The biggest common factor number is the GCF number.
So the greatest common factor 70,85 is 5.
Lets's calculate LCM of 558,4356
2 | 558, 4356 |
3 | 279, 2178 |
3 | 93, 726 |
31, 242 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 31 x 242 = 135036
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/135036
Therefore, the GCF of Fractions 70/558,85/4356 is 5/135036
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 558,4356 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(558,4356) = 18
common factors(in case of two or more numbers have common factors) = 1
GCF(558,4356) x common factors =18 x 1 = 18
LCM(558,4356) = ( 558 × 4356 ) / 18
LCM(558,4356) = 2430648 / 18
LCM(558,4356) = 135036
