Lets's calculate GCF of 115,715
5 | 115, 715 |
23, 143 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 115
:1,5,23,115
Now, list down the factors of 715
:1,5,11,13,55,65,143,715
Greatest Common Factor
We found the factors 115,715 . The biggest common factor number is the GCF number.
So the greatest common factor 115,715 is 5.
Lets's calculate LCM of 922,172
2 | 922, 172 |
461, 86 |
∴ So the LCM of the given numbers is 2 x 461 x 86 = 79292
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/79292
Therefore, the GCF of Fractions 115/922,715/172 is 5/79292
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 922,172 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(922,172) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(922,172) x common factors =2 x 1 = 2
LCM(922,172) = ( 922 × 172 ) / 2
LCM(922,172) = 158584 / 2
LCM(922,172) = 79292
