Greatest Common Factor
We found the factors 776,647 . The biggest common factor number is the GCF number.
So the greatest common factor 776,647 is 1.
Lets's calculate LCM of 666,663
3 | 666, 663 |
222, 221 |
∴ So the LCM of the given numbers is 3 x 222 x 221 = 147186
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/147186
Therefore, the GCF of Fractions 776/666,647/663 is 1/147186
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 666,663 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(666,663) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(666,663) x common factors =3 x 1 = 3
LCM(666,663) = ( 666 × 663 ) / 3
LCM(666,663) = 441558 / 3
LCM(666,663) = 147186
