Lets's calculate LCM of 561,636
3 | 561, 636 |
187, 212 |
∴ So the LCM of the given numbers is 3 x 187 x 212 = 118932
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/118932
Therefore, the GCF of Fractions 153/561,6690/636 is 3/118932
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 561,636 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(561,636) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(561,636) x common factors =3 x 1 = 3
LCM(561,636) = ( 561 × 636 ) / 3
LCM(561,636) = 356796 / 3
LCM(561,636) = 118932
