Lets's calculate LCM of 63,1656
3 | 63, 1656 |
3 | 21, 552 |
7, 184 |
∴ So the LCM of the given numbers is 3 x 3 x 7 x 184 = 11592
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/11592
Therefore, the GCF of Fractions 218/63,630/1656 is 2/11592
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 63,1656 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,1656) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(63,1656) x common factors =9 x 1 = 9
LCM(63,1656) = ( 63 × 1656 ) / 9
LCM(63,1656) = 104328 / 9
LCM(63,1656) = 11592
