Lets's calculate LCM of 918,249
3 | 918, 249 |
306, 83 |
∴ So the LCM of the given numbers is 3 x 306 x 83 = 76194
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/76194
Therefore, the GCF of Fractions 630/918,5415/249 is 15/76194
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 918,249 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(918,249) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(918,249) x common factors =3 x 1 = 3
LCM(918,249) = ( 918 × 249 ) / 3
LCM(918,249) = 228582 / 3
LCM(918,249) = 76194
