Lets's calculate LCM of 720,900
2 | 720, 900 |
2 | 360, 450 |
3 | 180, 225 |
3 | 60, 75 |
5 | 20, 25 |
4, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 5 x 4 x 5 = 3600
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3600
Therefore, the GCF of Fractions 836/720,691/900 is 1/3600
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 720,900 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(720,900) = 180
common factors(in case of two or more numbers have common factors) = 1
GCF(720,900) x common factors =180 x 1 = 180
LCM(720,900) = ( 720 × 900 ) / 180
LCM(720,900) = 648000 / 180
LCM(720,900) = 3600
