Greatest Common Factor
We found the factors 763,893 . The biggest common factor number is the GCF number.
So the greatest common factor 763,893 is 1.
Lets's calculate LCM of 380,778
2 | 380, 778 |
190, 389 |
∴ So the LCM of the given numbers is 2 x 190 x 389 = 147820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/147820
Therefore, the GCF of Fractions 763/380,893/778 is 1/147820
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 380,778 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(380,778) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(380,778) x common factors =2 x 1 = 2
LCM(380,778) = ( 380 × 778 ) / 2
LCM(380,778) = 295640 / 2
LCM(380,778) = 147820
