17 | 221, 816 |
13, 48 |
∴ So the GCF of the given numbers is 17 = 17
Now, list down the factors of 221
:1,13,17,221
Now, list down the factors of 816
:1,2,3,4,6,8,12,16,17,24,34,48,51,68,102,136,204,272,408,816
Greatest Common Factor
We found the factors 221,816 . The biggest common factor number is the GCF number.
So the greatest common factor 221,816 is 17.
Lets's calculate LCM of 680,531
Given numbers has no common factors except 1. So, there LCM is their product i.e 361080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/361080
Therefore, the GCF of Fractions 221/680,816/531 is 17/361080
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 680,531 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(680,531) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(680,531) x common factors =1 x 1 = 1
LCM(680,531) = ( 680 × 531 ) / 1
LCM(680,531) = 361080 / 1
LCM(680,531) = 361080
