Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 835/60,170/140
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 835,170
Greatest Common Factor of Numerators i.e. GCF of 835,170 is 5 .
LCM of Denominators means LCM of 60,140 as per the given fractions.
LCM of 60,140 is 420 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 835,170
5 | 835, 170 |
167, 34 |
∴ So the GCF of the given numbers is 5 = 5
Factors of 835
List of positive integer factors of 835 that divides 835 without a remainder.
1,5,167,835
Factors of 170
List of positive integer factors of 170 that divides 170 without a remainder.
1,2,5,10,17,34,85,170
Greatest Common Factor
We found the factors 835,170 . The biggest common factor number is the GCF number.
So the greatest common factor 835,170 is 5.
Lets's calculate LCM of 60,140
2 | 60, 140 |
2 | 30, 70 |
5 | 15, 35 |
3, 7 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 3 x 7 = 420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/420
Therefore, the GCF of Fractions 835/60,170/140 is 5/420
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 60,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(60,140) = 20
common factors(in case of two or more numbers have common factors) = 1
GCF(60,140) x common factors =20 x 1 = 20
LCM(60,140) = ( 60 × 140 ) / 20
LCM(60,140) = 8400 / 20
LCM(60,140) = 420
