Greatest Common Factor
We found the factors 32,84,548 . The biggest common factor number is the GCF number.
So the greatest common factor 32,84,548 is 4.
Lets's calculate LCM of 28,18,25
2 | 28, 18, 25 |
14, 9, 25 |
∴ So the LCM of the given numbers is 2 x 14 x 9 x 25 = 6300
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/6300
Therefore, the GCF of Fractions 32/28,84/18,548/25 is 4/6300
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 28,18,25 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,18,25) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(28,18,25) x common factors =1 x 2 = 2
LCM(28,18,25) = ( 28 × 18 × 25 ) / 2
LCM(28,18,25) = 12600 / 2
LCM(28,18,25) = 6300
