Lets's calculate GCF of 205,165
5 | 205, 165 |
41, 33 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 205
:1,5,41,205
Now, list down the factors of 165
:1,3,5,11,15,33,55,165
Greatest Common Factor
We found the factors 205,165 . The biggest common factor number is the GCF number.
So the greatest common factor 205,165 is 5.
Lets's calculate LCM of 60,126
2 | 60, 126 |
3 | 30, 63 |
10, 21 |
∴ So the LCM of the given numbers is 2 x 3 x 10 x 21 = 1260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/1260
Therefore, the GCF of Fractions 205/60,165/126 is 5/1260
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 60,126 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(60,126) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(60,126) x common factors =6 x 1 = 6
LCM(60,126) = ( 60 × 126 ) / 6
LCM(60,126) = 7560 / 6
LCM(60,126) = 1260
