Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 85/454,207/210
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 85,207
Greatest Common Factor of Numerators i.e. GCF of 85,207 is 1 .
LCM of Denominators means LCM of 454,210 as per the given fractions.
LCM of 454,210 is 47670 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 85,207
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 85
List of positive integer factors of 85 that divides 85 without a remainder.
1,5,17,85
Factors of 207
List of positive integer factors of 207 that divides 207 without a remainder.
1,3,9,23,69,207
Greatest Common Factor
We found the factors 85,207 . The biggest common factor number is the GCF number.
So the greatest common factor 85,207 is 1.
Lets's calculate LCM of 454,210
2 | 454, 210 |
227, 105 |
∴ So the LCM of the given numbers is 2 x 227 x 105 = 47670
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/47670
Therefore, the GCF of Fractions 85/454,207/210 is 1/47670
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 454,210 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(454,210) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(454,210) x common factors =2 x 1 = 2
LCM(454,210) = ( 454 × 210 ) / 2
LCM(454,210) = 95340 / 2
LCM(454,210) = 47670
