:1,821
Now, list down the factors of 145
:1,5,29,145
Greatest Common Factor
We found the factors 821,145 . The biggest common factor number is the GCF number.
So the greatest common factor 821,145 is 1.
Lets's calculate LCM of 967,149
Given numbers has no common factors except 1. So, there LCM is their product i.e 144083
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/144083
Therefore, the GCF of Fractions 821/967,145/149 is 1/144083
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 967,149 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(967,149) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(967,149) x common factors =1 x 1 = 1
LCM(967,149) = ( 967 × 149 ) / 1
LCM(967,149) = 144083 / 1
LCM(967,149) = 144083
