Greatest Common Factor
We found the factors 322,513,771 . The biggest common factor number is the GCF number.
So the greatest common factor 322,513,771 is 1.
Lets's calculate LCM of 21,52,144
2 | 21, 52, 144 |
2 | 21, 26, 72 |
3 | 21, 13, 36 |
7, 13, 12 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 13 x 12 = 13104
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/13104
Therefore, the GCF of Fractions 322/21,513/52,771/144 is 1/13104
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 21,52,144 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,52,144) = 1
common factors(in case of two or more numbers have common factors) = 12
GCF(21,52,144) x common factors =1 x 12 = 12
LCM(21,52,144) = ( 21 × 52 × 144 ) / 12
LCM(21,52,144) = 157248 / 12
LCM(21,52,144) = 13104
