Lets's calculate GCF of 19,1970
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 19
:1,19
Now, list down the factors of 1970
:1,2,5,10,197,394,985,1970
Greatest Common Factor
We found the factors 19,1970 . The biggest common factor number is the GCF number.
So the greatest common factor 19,1970 is 1.
Lets's calculate LCM of 205,2515
5 | 205, 2515 |
41, 503 |
∴ So the LCM of the given numbers is 5 x 41 x 503 = 103115
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/103115
Therefore, the GCF of Fractions 19/205,1970/2515 is 1/103115
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 205,2515 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(205,2515) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(205,2515) x common factors =5 x 1 = 5
LCM(205,2515) = ( 205 × 2515 ) / 5
LCM(205,2515) = 515575 / 5
LCM(205,2515) = 103115
