Lets's calculate GCF of 801,285
3 | 801, 285 |
267, 95 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 801
:1,3,9,89,267,801
Now, list down the factors of 285
:1,3,5,15,19,57,95,285
Greatest Common Factor
We found the factors 801,285 . The biggest common factor number is the GCF number.
So the greatest common factor 801,285 is 3.
Lets's calculate LCM of 906,961
Given numbers has no common factors except 1. So, there LCM is their product i.e 870666
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/870666
Therefore, the GCF of Fractions 801/906,285/961 is 3/870666
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 906,961 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(906,961) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(906,961) x common factors =1 x 1 = 1
LCM(906,961) = ( 906 × 961 ) / 1
LCM(906,961) = 870666 / 1
LCM(906,961) = 870666
