Greatest Common Factor
We found the factors 61,227,858 . The biggest common factor number is the GCF number.
So the greatest common factor 61,227,858 is 1.
Lets's calculate LCM of 34,87,405
3 | 34, 87, 405 |
34, 29, 135 |
∴ So the LCM of the given numbers is 3 x 34 x 29 x 135 = 399330
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/399330
Therefore, the GCF of Fractions 61/34,227/87,858/405 is 1/399330
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 34,87,405 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(34,87,405) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(34,87,405) x common factors =1 x 3 = 3
LCM(34,87,405) = ( 34 × 87 × 405 ) / 3
LCM(34,87,405) = 1197990 / 3
LCM(34,87,405) = 399330
