Lets's calculate GCF of 145,455
5 | 145, 455 |
29, 91 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 145
:1,5,29,145
Now, list down the factors of 455
:1,5,7,13,35,65,91,455
Greatest Common Factor
We found the factors 145,455 . The biggest common factor number is the GCF number.
So the greatest common factor 145,455 is 5.
Lets's calculate LCM of 803,789
Given numbers has no common factors except 1. So, there LCM is their product i.e 633567
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/633567
Therefore, the GCF of Fractions 145/803,455/789 is 5/633567
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 803,789 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(803,789) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(803,789) x common factors =1 x 1 = 1
LCM(803,789) = ( 803 × 789 ) / 1
LCM(803,789) = 633567 / 1
LCM(803,789) = 633567
