Lets's calculate GCF of 258,257
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 258
:1,2,3,6,43,86,129,258
Now, list down the factors of 257
:1,257
Greatest Common Factor
We found the factors 258,257 . The biggest common factor number is the GCF number.
So the greatest common factor 258,257 is 1.
Lets's calculate LCM of 722,651
Given numbers has no common factors except 1. So, there LCM is their product i.e 470022
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/470022
Therefore, the GCF of Fractions 258/722,257/651 is 1/470022
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 722,651 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(722,651) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(722,651) x common factors =1 x 1 = 1
LCM(722,651) = ( 722 × 651 ) / 1
LCM(722,651) = 470022 / 1
LCM(722,651) = 470022
