2 | 900, 434 |
450, 217 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 900
:1,2,3,4,5,6,9,10,12,15,18,20,25,30,36,45,50,60,75,90,100,150,180,225,300,450,900
Now, list down the factors of 434
:1,2,7,14,31,62,217,434
Greatest Common Factor
We found the factors 900,434 . The biggest common factor number is the GCF number.
So the greatest common factor 900,434 is 2.
Lets's calculate LCM of 643,909
Given numbers has no common factors except 1. So, there LCM is their product i.e 584487
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/584487
Therefore, the GCF of Fractions 900/643,434/909 is 2/584487
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 643,909 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(643,909) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(643,909) x common factors =1 x 1 = 1
LCM(643,909) = ( 643 × 909 ) / 1
LCM(643,909) = 584487 / 1
LCM(643,909) = 584487
