Lets's calculate GCF of 927,405
3 | 927, 405 |
3 | 309, 135 |
103, 45 |
∴ So the GCF of the given numbers is 3 x 3 = 9
Now, list down the factors of 927
:1,3,9,103,309,927
Now, list down the factors of 405
:1,3,5,9,15,27,45,81,135,405
Greatest Common Factor
We found the factors 927,405 . The biggest common factor number is the GCF number.
So the greatest common factor 927,405 is 9.
Lets's calculate LCM of 781,861
Given numbers has no common factors except 1. So, there LCM is their product i.e 672441
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/672441
Therefore, the GCF of Fractions 927/781,405/861 is 9/672441
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 781,861 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(781,861) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(781,861) x common factors =1 x 1 = 1
LCM(781,861) = ( 781 × 861 ) / 1
LCM(781,861) = 672441 / 1
LCM(781,861) = 672441
