Lets's calculate GCF of 345,580
5 | 345, 580 |
69, 116 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 345
:1,3,5,15,23,69,115,345
Now, list down the factors of 580
:1,2,4,5,10,20,29,58,116,145,290,580
Greatest Common Factor
We found the factors 345,580 . The biggest common factor number is the GCF number.
So the greatest common factor 345,580 is 5.
Lets's calculate LCM of 987,902
Given numbers has no common factors except 1. So, there LCM is their product i.e 890274
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/890274
Therefore, the GCF of Fractions 345/987,580/902 is 5/890274
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 987,902 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(987,902) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(987,902) x common factors =1 x 1 = 1
LCM(987,902) = ( 987 × 902 ) / 1
LCM(987,902) = 890274 / 1
LCM(987,902) = 890274
