Greatest Common Factor
We found the factors 981,634 . The biggest common factor number is the GCF number.
So the greatest common factor 981,634 is 1.
Lets's calculate LCM of 488,842
2 | 488, 842 |
244, 421 |
∴ So the LCM of the given numbers is 2 x 244 x 421 = 205448
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/205448
Therefore, the GCF of Fractions 981/488,634/842 is 1/205448
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 488,842 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(488,842) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(488,842) x common factors =2 x 1 = 2
LCM(488,842) = ( 488 × 842 ) / 2
LCM(488,842) = 410896 / 2
LCM(488,842) = 205448
