3 | 135, 870 |
5 | 45, 290 |
9, 58 |
∴ So the GCF of the given numbers is 3 x 5 = 15
Now, list down the factors of 135
:1,3,5,9,15,27,45,135
Now, list down the factors of 870
:1,2,3,5,6,10,15,29,30,58,87,145,174,290,435,870
Greatest Common Factor
We found the factors 135,870 . The biggest common factor number is the GCF number.
So the greatest common factor 135,870 is 15.
Lets's calculate LCM of 400,787
Given numbers has no common factors except 1. So, there LCM is their product i.e 314800
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/314800
Therefore, the GCF of Fractions 135/400,870/787 is 15/314800
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 400,787 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(400,787) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(400,787) x common factors =1 x 1 = 1
LCM(400,787) = ( 400 × 787 ) / 1
LCM(400,787) = 314800 / 1
LCM(400,787) = 314800
