5 | 655, 1815 |
131, 363 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 655
:1,5,131,655
Now, list down the factors of 1815
:1,3,5,11,15,33,55,121,165,363,605,1815
Greatest Common Factor
We found the factors 655,1815 . The biggest common factor number is the GCF number.
So the greatest common factor 655,1815 is 5.
Lets's calculate LCM of 822,643
Given numbers has no common factors except 1. So, there LCM is their product i.e 528546
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/528546
Therefore, the GCF of Fractions 655/822,1815/643 is 5/528546
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 822,643 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(822,643) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(822,643) x common factors =1 x 1 = 1
LCM(822,643) = ( 822 × 643 ) / 1
LCM(822,643) = 528546 / 1
LCM(822,643) = 528546
