Lets's calculate LCM of 507,6240
3 | 507, 6240 |
13 | 169, 2080 |
13, 160 |
∴ So the LCM of the given numbers is 3 x 13 x 13 x 160 = 81120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/81120
Therefore, the GCF of Fractions 905/507,8715/6240 is 5/81120
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 507,6240 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(507,6240) = 39
common factors(in case of two or more numbers have common factors) = 1
GCF(507,6240) x common factors =39 x 1 = 39
LCM(507,6240) = ( 507 × 6240 ) / 39
LCM(507,6240) = 3163680 / 39
LCM(507,6240) = 81120
