Lets's calculate GCF of 150,620
2 | 150, 620 |
5 | 75, 310 |
15, 62 |
∴ So the GCF of the given numbers is 2 x 5 = 10
Now, list down the factors of 150
:1,2,3,5,6,10,15,25,30,50,75,150
Now, list down the factors of 620
:1,2,4,5,10,20,31,62,124,155,310,620
Greatest Common Factor
We found the factors 150,620 . The biggest common factor number is the GCF number.
So the greatest common factor 150,620 is 10.
Lets's calculate LCM of 815,209
Given numbers has no common factors except 1. So, there LCM is their product i.e 170335
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/170335
Therefore, the GCF of Fractions 150/815,620/209 is 10/170335
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 815,209 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(815,209) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(815,209) x common factors =1 x 1 = 1
LCM(815,209) = ( 815 × 209 ) / 1
LCM(815,209) = 170335 / 1
LCM(815,209) = 170335
