Greatest Common Factor
We found the factors 50,72,418 . The biggest common factor number is the GCF number.
So the greatest common factor 50,72,418 is 2.
Lets's calculate LCM of 86,90,515
2 | 86, 90, 515 |
5 | 43, 45, 515 |
43, 9, 103 |
∴ So the LCM of the given numbers is 2 x 5 x 43 x 9 x 103 = 398610
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/398610
Therefore, the GCF of Fractions 50/86,72/90,418/515 is 2/398610
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 86,90,515 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,90,515) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(86,90,515) x common factors =1 x 10 = 10
LCM(86,90,515) = ( 86 × 90 × 515 ) / 10
LCM(86,90,515) = 3986100 / 10
LCM(86,90,515) = 398610
