Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 21/934,671/770
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 21,671
Greatest Common Factor of Numerators i.e. GCF of 21,671 is 1 .
LCM of Denominators means LCM of 934,770 as per the given fractions.
LCM of 934,770 is 359590 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 21,671
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 21
List of positive integer factors of 21 that divides 21 without a remainder.
1,3,7,21
Factors of 671
List of positive integer factors of 671 that divides 671 without a remainder.
1,11,61,671
Greatest Common Factor
We found the factors 21,671 . The biggest common factor number is the GCF number.
So the greatest common factor 21,671 is 1.
Lets's calculate LCM of 934,770
2 | 934, 770 |
467, 385 |
∴ So the LCM of the given numbers is 2 x 467 x 385 = 359590
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/359590
Therefore, the GCF of Fractions 21/934,671/770 is 1/359590
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 934,770 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(934,770) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(934,770) x common factors =2 x 1 = 2
LCM(934,770) = ( 934 × 770 ) / 2
LCM(934,770) = 719180 / 2
LCM(934,770) = 359590
