Lets's calculate GCF of 882,819
3 | 882, 819 |
3 | 294, 273 |
7 | 98, 91 |
14, 13 |
∴ So the GCF of the given numbers is 3 x 3 x 7 = 63
Now, list down the factors of 882
:1,2,3,6,7,9,14,18,21,42,49,63,98,126,147,294,441,882
Now, list down the factors of 819
:1,3,7,9,13,21,39,63,91,117,273,819
Greatest Common Factor
We found the factors 882,819 . The biggest common factor number is the GCF number.
So the greatest common factor 882,819 is 63.
Lets's calculate LCM of 12,391
Given numbers has no common factors except 1. So, there LCM is their product i.e 4692
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 63/4692
Therefore, the GCF of Fractions 882/12,819/391 is 63/4692
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 12,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(12,391) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(12,391) x common factors =1 x 1 = 1
LCM(12,391) = ( 12 × 391 ) / 1
LCM(12,391) = 4692 / 1
LCM(12,391) = 4692
