So the greatest common factor 84,642,388 is 2.
Lets's calculate LCM of 62,73,470
2 | 62, 73, 470 |
31, 73, 235 |
∴ So the LCM of the given numbers is 2 x 31 x 73 x 235 = 1063610
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1063610
Therefore, the GCF of Fractions 84/62,642/73,388/470 is 2/1063610
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 62,73,470 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(62,73,470) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(62,73,470) x common factors =1 x 2 = 2
LCM(62,73,470) = ( 62 × 73 × 470 ) / 2
LCM(62,73,470) = 2127220 / 2
LCM(62,73,470) = 1063610
