∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 731
:1,17,43,731
Now, list down the factors of 309
:1,3,103,309
Greatest Common Factor
We found the factors 731,309 . The biggest common factor number is the GCF number.
So the greatest common factor 731,309 is 1.
Lets's calculate LCM of 85,460
5 | 85, 460 |
17, 92 |
∴ So the LCM of the given numbers is 5 x 17 x 92 = 7820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7820
Therefore, the GCF of Fractions 731/85,309/460 is 1/7820
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 85,460 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,460) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(85,460) x common factors =5 x 1 = 5
LCM(85,460) = ( 85 × 460 ) / 5
LCM(85,460) = 39100 / 5
LCM(85,460) = 7820
