Greatest Common Factor
We found the factors 990,605 . The biggest common factor number is the GCF number.
So the greatest common factor 990,605 is 55.
Lets's calculate LCM of 978,852
2 | 978, 852 |
3 | 489, 426 |
163, 142 |
∴ So the LCM of the given numbers is 2 x 3 x 163 x 142 = 138876
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 55/138876
Therefore, the GCF of Fractions 990/978,605/852 is 55/138876
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 978,852 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(978,852) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(978,852) x common factors =6 x 1 = 6
LCM(978,852) = ( 978 × 852 ) / 6
LCM(978,852) = 833256 / 6
LCM(978,852) = 138876
