∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 920
:1,2,4,5,8,10,20,23,40,46,92,115,184,230,460,920
Now, list down the factors of 159
:1,3,53,159
Greatest Common Factor
We found the factors 920,159 . The biggest common factor number is the GCF number.
So the greatest common factor 920,159 is 1.
Lets's calculate LCM of 915,425
5 | 915, 425 |
183, 85 |
∴ So the LCM of the given numbers is 5 x 183 x 85 = 77775
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/77775
Therefore, the GCF of Fractions 920/915,159/425 is 1/77775
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 915,425 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(915,425) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(915,425) x common factors =5 x 1 = 5
LCM(915,425) = ( 915 × 425 ) / 5
LCM(915,425) = 388875 / 5
LCM(915,425) = 77775
