Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 921/966,278/210
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 921,278
Greatest Common Factor of Numerators i.e. GCF of 921,278 is 1 .
LCM of Denominators means LCM of 966,210 as per the given fractions.
LCM of 966,210 is 4830 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 921,278
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 921 that divides 921 without a remainder.
1,3,307,921
Factors of 278
List of positive integer factors of 278 that divides 278 without a remainder.
1,2,139,278
Greatest Common Factor
We found the factors 921,278 . The biggest common factor number is the GCF number.
So the greatest common factor 921,278 is 1.
Lets's calculate LCM of 966,210
2 | 966, 210 |
3 | 483, 105 |
7 | 161, 35 |
23, 5 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 23 x 5 = 4830
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4830
Therefore, the GCF of Fractions 921/966,278/210 is 1/4830
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 966,210 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(966,210) = 42
common factors(in case of two or more numbers have common factors) = 1
GCF(966,210) x common factors =42 x 1 = 42
LCM(966,210) = ( 966 × 210 ) / 42
LCM(966,210) = 202860 / 42
LCM(966,210) = 4830
