Lets's calculate LCM of 441,531,697
3 | 441, 531, 697 |
3 | 147, 177, 697 |
49, 59, 697 |
∴ So the LCM of the given numbers is 3 x 3 x 49 x 59 x 697 = 18135243
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/18135243
Therefore, the GCF of Fractions 98/441,12/531,680/697 is 2/18135243
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 441,531,697 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(441,531,697) = 1
common factors(in case of two or more numbers have common factors) = 9
GCF(441,531,697) x common factors =1 x 9 = 9
LCM(441,531,697) = ( 441 × 531 × 697 ) / 9
LCM(441,531,697) = 163217187 / 9
LCM(441,531,697) = 18135243
