Greatest Common Factor
We found the factors 421,235,390 . The biggest common factor number is the GCF number.
So the greatest common factor 421,235,390 is 1.
Lets's calculate LCM of 75,28,716
2 | 75, 28, 716 |
2 | 75, 14, 358 |
75, 7, 179 |
∴ So the LCM of the given numbers is 2 x 2 x 75 x 7 x 179 = 375900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/375900
Therefore, the GCF of Fractions 421/75,235/28,390/716 is 1/375900
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 75,28,716 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(75,28,716) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(75,28,716) x common factors =1 x 4 = 4
LCM(75,28,716) = ( 75 × 28 × 716 ) / 4
LCM(75,28,716) = 1503600 / 4
LCM(75,28,716) = 375900
