Lets's calculate GCF of 254,511
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 254
:1,2,127,254
Now, list down the factors of 511
:1,7,73,511
Greatest Common Factor
We found the factors 254,511 . The biggest common factor number is the GCF number.
So the greatest common factor 254,511 is 1.
Lets's calculate LCM of 287,974
Given numbers has no common factors except 1. So, there LCM is their product i.e 279538
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/279538
Therefore, the GCF of Fractions 254/287,511/974 is 1/279538
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 287,974 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(287,974) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(287,974) x common factors =1 x 1 = 1
LCM(287,974) = ( 287 × 974 ) / 1
LCM(287,974) = 279538 / 1
LCM(287,974) = 279538
