So the greatest common factor 65,403,494 is 13.
Lets's calculate LCM of 74,85,540
2 | 74, 85, 540 |
5 | 37, 85, 270 |
37, 17, 54 |
∴ So the LCM of the given numbers is 2 x 5 x 37 x 17 x 54 = 339660
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/339660
Therefore, the GCF of Fractions 65/74,403/85,494/540 is 13/339660
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 74,85,540 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(74,85,540) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(74,85,540) x common factors =1 x 10 = 10
LCM(74,85,540) = ( 74 × 85 × 540 ) / 10
LCM(74,85,540) = 3396600 / 10
LCM(74,85,540) = 339660
