Lets's calculate LCM of 63,8865
3 | 63, 8865 |
3 | 21, 2955 |
7, 985 |
∴ So the LCM of the given numbers is 3 x 3 x 7 x 985 = 62055
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 23/62055
Therefore, the GCF of Fractions 989/63,690/8865 is 23/62055
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 63,8865 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,8865) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(63,8865) x common factors =9 x 1 = 9
LCM(63,8865) = ( 63 × 8865 ) / 9
LCM(63,8865) = 558495 / 9
LCM(63,8865) = 62055
