Greatest Common Factor
We found the factors 13,492,258 . The biggest common factor number is the GCF number.
So the greatest common factor 13,492,258 is 1.
Lets's calculate LCM of 11,56,308
2 | 11, 56, 308 |
2 | 11, 28, 154 |
7 | 11, 14, 77 |
11 | 11, 2, 11 |
1, 2, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 11 x 1 x 2 x 1 = 616
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/616
Therefore, the GCF of Fractions 13/11,492/56,258/308 is 1/616
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 11,56,308 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(11,56,308) = 1
common factors(in case of two or more numbers have common factors) = 308
GCF(11,56,308) x common factors =1 x 308 = 308
LCM(11,56,308) = ( 11 × 56 × 308 ) / 308
LCM(11,56,308) = 189728 / 308
LCM(11,56,308) = 616
