Lets's calculate GCF of 891,915
3 | 891, 915 |
297, 305 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 891
:1,3,9,11,27,33,81,99,297,891
Now, list down the factors of 915
:1,3,5,15,61,183,305,915
Greatest Common Factor
We found the factors 891,915 . The biggest common factor number is the GCF number.
So the greatest common factor 891,915 is 3.
Lets's calculate LCM of 601,688
Given numbers has no common factors except 1. So, there LCM is their product i.e 413488
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/413488
Therefore, the GCF of Fractions 891/601,915/688 is 3/413488
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 601,688 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(601,688) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(601,688) x common factors =1 x 1 = 1
LCM(601,688) = ( 601 × 688 ) / 1
LCM(601,688) = 413488 / 1
LCM(601,688) = 413488
