Lets's calculate GCF of 417,222
3 | 417, 222 |
139, 74 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 417
:1,3,139,417
Now, list down the factors of 222
:1,2,3,6,37,74,111,222
Greatest Common Factor
We found the factors 417,222 . The biggest common factor number is the GCF number.
So the greatest common factor 417,222 is 3.
Lets's calculate LCM of 412,991
Given numbers has no common factors except 1. So, there LCM is their product i.e 408292
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/408292
Therefore, the GCF of Fractions 417/412,222/991 is 3/408292
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 412,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(412,991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(412,991) x common factors =1 x 1 = 1
LCM(412,991) = ( 412 × 991 ) / 1
LCM(412,991) = 408292 / 1
LCM(412,991) = 408292
