Lets's calculate LCM of 15,98,958
2 | 15, 98, 958 |
15, 49, 479 |
∴ So the LCM of the given numbers is 2 x 15 x 49 x 479 = 704130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/704130
Therefore, the GCF of Fractions 31/15,624/98,120/958 is 1/704130
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 15,98,958 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,98,958) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(15,98,958) x common factors =1 x 2 = 2
LCM(15,98,958) = ( 15 × 98 × 958 ) / 2
LCM(15,98,958) = 1408260 / 2
LCM(15,98,958) = 704130
