Lets's calculate LCM of 305,8470
5 | 305, 8470 |
61, 1694 |
∴ So the LCM of the given numbers is 5 x 61 x 1694 = 516670
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/516670
Therefore, the GCF of Fractions 2775/305,7140/8470 is 15/516670
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 305,8470 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(305,8470) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(305,8470) x common factors =5 x 1 = 5
LCM(305,8470) = ( 305 × 8470 ) / 5
LCM(305,8470) = 2583350 / 5
LCM(305,8470) = 516670
