Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 5/61,980/90,915/70
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 5,980,915
Greatest Common Factor of Numerators i.e. GCF of 5,980,915 is 5 .
LCM of Denominators means LCM of 61,90,70 as per the given fractions.
LCM of 61,90,70 is 38430 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 5,980,915
5 | 5, 980, 915 |
1, 196, 183 |
∴ So the GCF of the given numbers is 5 = 5

Greatest Common Factor
We found the factors 5,980,915 . The biggest common factor number is the GCF number.
So the greatest common factor 5,980,915 is 5.
Lets's calculate LCM of 61,90,70
2 | 61, 90, 70 |
5 | 61, 45, 35 |
61, 9, 7 |
∴ So the LCM of the given numbers is 2 x 5 x 61 x 9 x 7 = 38430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/38430
Therefore, the GCF of Fractions 5/61,980/90,915/70 is 5/38430
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 61,90,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,90,70) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(61,90,70) x common factors =1 x 10 = 10
LCM(61,90,70) = ( 61 × 90 × 70 ) / 10
LCM(61,90,70) = 384300 / 10
LCM(61,90,70) = 38430
