Greatest Common Factor
We found the factors 4,90,85,618 . The biggest common factor number is the GCF number.
So the greatest common factor 4,90,85,618 is 1.
Lets's calculate LCM of 14,10,185,945
2 | 14, 10, 185, 945 |
5 | 7, 5, 185, 945 |
7 | 7, 1, 37, 189 |
1, 1, 37, 27 |
∴ So the LCM of the given numbers is 2 x 5 x 7 x 1 x 1 x 37 x 27 = 69930
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/69930
Therefore, the GCF of Fractions 4/14,90/10,85/185,618/945 is 1/69930
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 14,10,185,945 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(14,10,185,945) = 1
common factors(in case of two or more numbers have common factors) = 350
GCF(14,10,185,945) x common factors =1 x 350 = 350
LCM(14,10,185,945) = ( 14 × 10 × 185 × 945 ) / 350
LCM(14,10,185,945) = 24475500 / 350
LCM(14,10,185,945) = 69930
