Greatest Common Factor
We found the factors 63,183,717 . The biggest common factor number is the GCF number.
So the greatest common factor 63,183,717 is 3.
Lets's calculate LCM of 70,18,647
2 | 70, 18, 647 |
35, 9, 647 |
∴ So the LCM of the given numbers is 2 x 35 x 9 x 647 = 407610
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/407610
Therefore, the GCF of Fractions 63/70,183/18,717/647 is 3/407610
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 70,18,647 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,18,647) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(70,18,647) x common factors =1 x 2 = 2
LCM(70,18,647) = ( 70 × 18 × 647 ) / 2
LCM(70,18,647) = 815220 / 2
LCM(70,18,647) = 407610
