Greatest Common Factor
We found the factors 20,885,217 . The biggest common factor number is the GCF number.
So the greatest common factor 20,885,217 is 1.
Lets's calculate LCM of 300,968,419
2 | 300, 968, 419 |
2 | 150, 484, 419 |
75, 242, 419 |
∴ So the LCM of the given numbers is 2 x 2 x 75 x 242 x 419 = 30419400
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30419400
Therefore, the GCF of Fractions 20/300,885/968,217/419 is 1/30419400
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 300,968,419 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(300,968,419) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(300,968,419) x common factors =1 x 4 = 4
LCM(300,968,419) = ( 300 × 968 × 419 ) / 4
LCM(300,968,419) = 121677600 / 4
LCM(300,968,419) = 30419400
