Greatest Common Factor
We found the factors 38,791,688 . The biggest common factor number is the GCF number.
So the greatest common factor 38,791,688 is 1.
Lets's calculate LCM of 32,16,958
2 | 32, 16, 958 |
2 | 16, 8, 479 |
2 | 4, 8, 479 |
2 | 2, 4, 479 |
1, 2, 479 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 1 x 2 x 479 = 15328
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/15328
Therefore, the GCF of Fractions 38/32,791/16,688/958 is 1/15328
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 32,16,958 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(32,16,958) = 2
common factors(in case of two or more numbers have common factors) = 16
GCF(32,16,958) x common factors =2 x 16 = 32
LCM(32,16,958) = ( 32 × 16 × 958 ) / 32
LCM(32,16,958) = 490496 / 32
LCM(32,16,958) = 15328
