Lets's calculate LCM of 507,117
3 | 507, 117 |
13 | 169, 39 |
13, 3 |
∴ So the LCM of the given numbers is 3 x 13 x 13 x 3 = 1521
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1521
Therefore, the GCF of Fractions 802/507,722/117 is 2/1521
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 507,117 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(507,117) = 39
common factors(in case of two or more numbers have common factors) = 1
GCF(507,117) x common factors =39 x 1 = 39
LCM(507,117) = ( 507 × 117 ) / 39
LCM(507,117) = 59319 / 39
LCM(507,117) = 1521
