Greatest Common Factor
We found the factors 810,388 . The biggest common factor number is the GCF number.
So the greatest common factor 810,388 is 2.
Lets's calculate LCM of 70,762
2 | 70, 762 |
35, 381 |
∴ So the LCM of the given numbers is 2 x 35 x 381 = 26670
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/26670
Therefore, the GCF of Fractions 810/70,388/762 is 2/26670
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 70,762 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,762) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(70,762) x common factors =2 x 1 = 2
LCM(70,762) = ( 70 × 762 ) / 2
LCM(70,762) = 53340 / 2
LCM(70,762) = 26670
