Lets's calculate GCF of 425,2091
17 | 425, 2091 |
25, 123 |
∴ So the GCF of the given numbers is 17 = 17
Now, list down the factors of 425
:1,5,17,25,85,425
Now, list down the factors of 2091
:1,3,17,41,51,123,697,2091
Greatest Common Factor
We found the factors 425,2091 . The biggest common factor number is the GCF number.
So the greatest common factor 425,2091 is 17.
Lets's calculate LCM of 247,1646
Given numbers has no common factors except 1. So, there LCM is their product i.e 406562
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/406562
Therefore, the GCF of Fractions 425/247,2091/1646 is 17/406562
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 247,1646 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(247,1646) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(247,1646) x common factors =1 x 1 = 1
LCM(247,1646) = ( 247 × 1646 ) / 1
LCM(247,1646) = 406562 / 1
LCM(247,1646) = 406562
