Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 407/692,399/820
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 407,399
Greatest Common Factor of Numerators i.e. GCF of 407,399 is 1 .
LCM of Denominators means LCM of 692,820 as per the given fractions.
LCM of 692,820 is 141860 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 407,399
∴ So GCF of numbers is 1 because of no common factors present between them.

1,3,7,19,21,57,133,399
Greatest Common Factor
We found the factors 407,399 . The biggest common factor number is the GCF number.
So the greatest common factor 407,399 is 1.
Lets's calculate LCM of 692,820
2 | 692, 820 |
2 | 346, 410 |
173, 205 |
∴ So the LCM of the given numbers is 2 x 2 x 173 x 205 = 141860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/141860
Therefore, the GCF of Fractions 407/692,399/820 is 1/141860
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 692,820 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(692,820) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(692,820) x common factors =4 x 1 = 4
LCM(692,820) = ( 692 × 820 ) / 4
LCM(692,820) = 567440 / 4
LCM(692,820) = 141860
