Greatest Common Factor
We found the factors 204,635 . The biggest common factor number is the GCF number.
So the greatest common factor 204,635 is 1.
Lets's calculate LCM of 70,390
2 | 70, 390 |
5 | 35, 195 |
7, 39 |
∴ So the LCM of the given numbers is 2 x 5 x 7 x 39 = 2730
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2730
Therefore, the GCF of Fractions 204/70,635/390 is 1/2730
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 70,390 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,390) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(70,390) x common factors =10 x 1 = 10
LCM(70,390) = ( 70 × 390 ) / 10
LCM(70,390) = 27300 / 10
LCM(70,390) = 2730
