Greatest Common Factor
We found the factors 42,50,869 . The biggest common factor number is the GCF number.
So the greatest common factor 42,50,869 is 1.
Lets's calculate LCM of 864,872,615
2 | 864, 872, 615 |
2 | 432, 436, 615 |
2 | 216, 218, 615 |
3 | 108, 109, 615 |
36, 109, 205 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 36 x 109 x 205 = 19306080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19306080
Therefore, the GCF of Fractions 42/864,50/872,869/615 is 1/19306080
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 864,872,615 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(864,872,615) = 1
common factors(in case of two or more numbers have common factors) = 24
GCF(864,872,615) x common factors =1 x 24 = 24
LCM(864,872,615) = ( 864 × 872 × 615 ) / 24
LCM(864,872,615) = 463345920 / 24
LCM(864,872,615) = 19306080
