Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 669/79,381/921
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 669,381
Greatest Common Factor of Numerators i.e. GCF of 669,381 is 3 .
LCM of Denominators means LCM of 79,921 as per the given fractions.
LCM of 79,921 is 72759 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 669,381
3 | 669, 381 |
223, 127 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 669
List of positive integer factors of 669 that divides 669 without a remainder.
1,3,223,669
Factors of 381
List of positive integer factors of 381 that divides 381 without a remainder.
1,3,127,381
Greatest Common Factor
We found the factors 669,381 . The biggest common factor number is the GCF number.
So the greatest common factor 669,381 is 3.
Lets's calculate LCM of 79,921
Given numbers has no common factors except 1. So, there LCM is their product i.e 72759
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/72759
Therefore, the GCF of Fractions 669/79,381/921 is 3/72759
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 79,921 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,921) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,921) x common factors =1 x 1 = 1
LCM(79,921) = ( 79 × 921 ) / 1
LCM(79,921) = 72759 / 1
LCM(79,921) = 72759
