Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 100/949,216/689
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 100,216
Greatest Common Factor of Numerators i.e. GCF of 100,216 is 4 .
LCM of Denominators means LCM of 949,689 as per the given fractions.
LCM of 949,689 is 50297 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 100,216
2 | 100, 216 |
2 | 50, 108 |
25, 54 |
∴ So the GCF of the given numbers is 2 x 2 = 4

1,2,3,4,6,8,9,12,18,24,27,36,54,72,108,216
Greatest Common Factor
We found the factors 100,216 . The biggest common factor number is the GCF number.
So the greatest common factor 100,216 is 4.
Lets's calculate LCM of 949,689
13 | 949, 689 |
73, 53 |
∴ So the LCM of the given numbers is 13 x 73 x 53 = 50297
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/50297
Therefore, the GCF of Fractions 100/949,216/689 is 4/50297
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 949,689 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(949,689) = 13
common factors(in case of two or more numbers have common factors) = 1
GCF(949,689) x common factors =13 x 1 = 13
LCM(949,689) = ( 949 × 689 ) / 13
LCM(949,689) = 653861 / 13
LCM(949,689) = 50297
