Lets's calculate GCF of 201,257
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 201
:1,3,67,201
Now, list down the factors of 257
:1,257
Greatest Common Factor
We found the factors 201,257 . The biggest common factor number is the GCF number.
So the greatest common factor 201,257 is 1.
Lets's calculate LCM of 140,281
Given numbers has no common factors except 1. So, there LCM is their product i.e 39340
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/39340
Therefore, the GCF of Fractions 201/140,257/281 is 1/39340
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 140,281 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(140,281) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(140,281) x common factors =1 x 1 = 1
LCM(140,281) = ( 140 × 281 ) / 1
LCM(140,281) = 39340 / 1
LCM(140,281) = 39340
