Lets's calculate GCF of 425,665
5 | 425, 665 |
85, 133 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 425
:1,5,17,25,85,425
Now, list down the factors of 665
:1,5,7,19,35,95,133,665
Greatest Common Factor
We found the factors 425,665 . The biggest common factor number is the GCF number.
So the greatest common factor 425,665 is 5.
Lets's calculate LCM of 74,924
2 | 74, 924 |
37, 462 |
∴ So the LCM of the given numbers is 2 x 37 x 462 = 34188
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/34188
Therefore, the GCF of Fractions 425/74,665/924 is 5/34188
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 74,924 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(74,924) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(74,924) x common factors =2 x 1 = 2
LCM(74,924) = ( 74 × 924 ) / 2
LCM(74,924) = 68376 / 2
LCM(74,924) = 34188
