Greatest Common Factor
We found the factors 648,253 . The biggest common factor number is the GCF number.
So the greatest common factor 648,253 is 1.
Lets's calculate LCM of 435,790
5 | 435, 790 |
87, 158 |
∴ So the LCM of the given numbers is 5 x 87 x 158 = 68730
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/68730
Therefore, the GCF of Fractions 648/435,253/790 is 1/68730
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 435,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(435,790) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(435,790) x common factors =5 x 1 = 5
LCM(435,790) = ( 435 × 790 ) / 5
LCM(435,790) = 343650 / 5
LCM(435,790) = 68730
