Greatest Common Factor
We found the factors 621,540 . The biggest common factor number is the GCF number.
So the greatest common factor 621,540 is 27.
Lets's calculate LCM of 28,889
7 | 28, 889 |
4, 127 |
∴ So the LCM of the given numbers is 7 x 4 x 127 = 3556
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 27/3556
Therefore, the GCF of Fractions 621/28,540/889 is 27/3556
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 28,889 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,889) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(28,889) x common factors =7 x 1 = 7
LCM(28,889) = ( 28 × 889 ) / 7
LCM(28,889) = 24892 / 7
LCM(28,889) = 3556
