Lets's calculate GCF of 631,864
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 631
:1,631
Now, list down the factors of 864
:1,2,3,4,6,8,9,12,16,18,24,27,32,36,48,54,72,96,108,144,216,288,432,864
Greatest Common Factor
We found the factors 631,864 . The biggest common factor number is the GCF number.
So the greatest common factor 631,864 is 1.
Lets's calculate LCM of 455,201
Given numbers has no common factors except 1. So, there LCM is their product i.e 91455
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/91455
Therefore, the GCF of Fractions 631/455,864/201 is 1/91455
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 455,201 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(455,201) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(455,201) x common factors =1 x 1 = 1
LCM(455,201) = ( 455 × 201 ) / 1
LCM(455,201) = 91455 / 1
LCM(455,201) = 91455
