Greatest Common Factor
We found the factors 825,7869 . The biggest common factor number is the GCF number.
So the greatest common factor 825,7869 is 3.
Lets's calculate LCM of 945,816
3 | 945, 816 |
315, 272 |
∴ So the LCM of the given numbers is 3 x 315 x 272 = 257040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/257040
Therefore, the GCF of Fractions 825/945,7869/816 is 3/257040
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 945,816 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(945,816) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(945,816) x common factors =3 x 1 = 3
LCM(945,816) = ( 945 × 816 ) / 3
LCM(945,816) = 771120 / 3
LCM(945,816) = 257040
