Greatest Common Factor
We found the factors 678,745,655 . The biggest common factor number is the GCF number.
So the greatest common factor 678,745,655 is 1.
Lets's calculate LCM of 85,10,16
2 | 85, 10, 16 |
5 | 85, 5, 8 |
17, 1, 8 |
∴ So the LCM of the given numbers is 2 x 5 x 17 x 1 x 8 = 1360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1360
Therefore, the GCF of Fractions 678/85,745/10,655/16 is 1/1360
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 85,10,16 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,10,16) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(85,10,16) x common factors =1 x 10 = 10
LCM(85,10,16) = ( 85 × 10 × 16 ) / 10
LCM(85,10,16) = 13600 / 10
LCM(85,10,16) = 1360
