Lets's calculate GCF of 791,574
7 | 791, 574 |
113, 82 |
∴ So the GCF of the given numbers is 7 = 7
Now, list down the factors of 791
:1,7,113,791
Now, list down the factors of 574
:1,2,7,14,41,82,287,574
Greatest Common Factor
We found the factors 791,574 . The biggest common factor number is the GCF number.
So the greatest common factor 791,574 is 7.
Lets's calculate LCM of 823,638
Given numbers has no common factors except 1. So, there LCM is their product i.e 525074
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/525074
Therefore, the GCF of Fractions 791/823,574/638 is 7/525074
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 823,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(823,638) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(823,638) x common factors =1 x 1 = 1
LCM(823,638) = ( 823 × 638 ) / 1
LCM(823,638) = 525074 / 1
LCM(823,638) = 525074
