Greatest Common Factor
We found the factors 235,864,228 . The biggest common factor number is the GCF number.
So the greatest common factor 235,864,228 is 1.
Lets's calculate LCM of 28,28,987
2 | 28, 28, 987 |
2 | 14, 14, 987 |
7 | 7, 7, 987 |
1, 1, 141 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 1 x 1 x 141 = 3948
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3948
Therefore, the GCF of Fractions 235/28,864/28,228/987 is 1/3948
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 28,28,987 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,28,987) = 7
common factors(in case of two or more numbers have common factors) = 28
GCF(28,28,987) x common factors =7 x 28 = 196
LCM(28,28,987) = ( 28 × 28 × 987 ) / 196
LCM(28,28,987) = 773808 / 196
LCM(28,28,987) = 3948
