Now, list down the factors of 691
:1,691
Greatest Common Factor
We found the factors 764,691 . The biggest common factor number is the GCF number.
So the greatest common factor 764,691 is 1.
Lets's calculate LCM of 303,315
3 | 303, 315 |
101, 105 |
∴ So the LCM of the given numbers is 3 x 101 x 105 = 31815
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/31815
Therefore, the GCF of Fractions 764/303,691/315 is 1/31815
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 303,315 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(303,315) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(303,315) x common factors =3 x 1 = 3
LCM(303,315) = ( 303 × 315 ) / 3
LCM(303,315) = 95445 / 3
LCM(303,315) = 31815
