2 | 412, 260 |
2 | 206, 130 |
103, 65 |
∴ So the GCF of the given numbers is 2 x 2 = 4
Now, list down the factors of 412
:1,2,4,103,206,412
Now, list down the factors of 260
:1,2,4,5,10,13,20,26,52,65,130,260
Greatest Common Factor
We found the factors 412,260 . The biggest common factor number is the GCF number.
So the greatest common factor 412,260 is 4.
Lets's calculate LCM of 585,790
5 | 585, 790 |
117, 158 |
∴ So the LCM of the given numbers is 5 x 117 x 158 = 92430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/92430
Therefore, the GCF of Fractions 412/585,260/790 is 4/92430
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 585,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(585,790) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(585,790) x common factors =5 x 1 = 5
LCM(585,790) = ( 585 × 790 ) / 5
LCM(585,790) = 462150 / 5
LCM(585,790) = 92430
