Greatest Common Factor
We found the factors 15,99,379 . The biggest common factor number is the GCF number.
So the greatest common factor 15,99,379 is 1.
Lets's calculate LCM of 45,21,196
3 | 45, 21, 196 |
7 | 15, 7, 196 |
15, 1, 28 |
∴ So the LCM of the given numbers is 3 x 7 x 15 x 1 x 28 = 8820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8820
Therefore, the GCF of Fractions 15/45,99/21,379/196 is 1/8820
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 45,21,196 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,21,196) = 1
common factors(in case of two or more numbers have common factors) = 21
GCF(45,21,196) x common factors =1 x 21 = 21
LCM(45,21,196) = ( 45 × 21 × 196 ) / 21
LCM(45,21,196) = 185220 / 21
LCM(45,21,196) = 8820
