7 | 805, 861 |
115, 123 |
∴ So the GCF of the given numbers is 7 = 7
Now, list down the factors of 805
:1,5,7,23,35,115,161,805
Now, list down the factors of 861
:1,3,7,21,41,123,287,861
Greatest Common Factor
We found the factors 805,861 . The biggest common factor number is the GCF number.
So the greatest common factor 805,861 is 7.
Lets's calculate LCM of 266,513
19 | 266, 513 |
14, 27 |
∴ So the LCM of the given numbers is 19 x 14 x 27 = 7182
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/7182
Therefore, the GCF of Fractions 805/266,861/513 is 7/7182
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 266,513 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(266,513) = 19
common factors(in case of two or more numbers have common factors) = 1
GCF(266,513) x common factors =19 x 1 = 19
LCM(266,513) = ( 266 × 513 ) / 19
LCM(266,513) = 136458 / 19
LCM(266,513) = 7182
