Lets's calculate GCF of 665,285
5 | 665, 285 |
19 | 133, 57 |
7, 3 |
∴ So the GCF of the given numbers is 5 x 19 = 95
Now, list down the factors of 665
:1,5,7,19,35,95,133,665
Now, list down the factors of 285
:1,3,5,15,19,57,95,285
Greatest Common Factor
We found the factors 665,285 . The biggest common factor number is the GCF number.
So the greatest common factor 665,285 is 95.
Lets's calculate LCM of 49,1231
Given numbers has no common factors except 1. So, there LCM is their product i.e 60319
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 95/60319
Therefore, the GCF of Fractions 665/49,285/1231 is 95/60319
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 49,1231 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,1231) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(49,1231) x common factors =1 x 1 = 1
LCM(49,1231) = ( 49 × 1231 ) / 1
LCM(49,1231) = 60319 / 1
LCM(49,1231) = 60319
