Lets's calculate GCF of 242,698
| 2 | 242, 698 |
| 121, 349 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 242
:1,2,11,22,121,242
Now, list down the factors of 698
:1,2,349,698
Greatest Common Factor
We found the factors 242,698 . The biggest common factor number is the GCF number.
So the greatest common factor 242,698 is 2.
Lets's calculate LCM of 39,403
| 13 | 39, 403 |
| 3, 31 |
∴ So the LCM of the given numbers is 13 x 3 x 31 = 1209
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1209
Therefore, the GCF of Fractions 242/39,698/403 is 2/1209
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 39,403 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,403) = 13
common factors(in case of two or more numbers have common factors) = 1
GCF(39,403) x common factors =13 x 1 = 13
LCM(39,403) = ( 39 × 403 ) / 13
LCM(39,403) = 15717 / 13
LCM(39,403) = 1209
