The HCF of 209,253 is 11.
Lets's calculate GCF of 209,253
11 | 209, 253 |
19, 23 |
∴ So the GCF of the given numbers is 11 = 11
Now, list down the factors of 209
:1,11,19,209
Now, list down the factors of 253
:1,11,23,253
Greatest Common Factor
We found the factors 209,253 . The biggest common factor number is the GCF number.
So the greatest common factor 209,253 is 11.
Lets's calculate LCM of 857,125
Given numbers has no common factors except 1. So, there LCM is their product i.e 107125
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/107125
Therefore, the GCF of Fractions 209/857,253/125 is 11/107125
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 857,125 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(857,125) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(857,125) x common factors =1 x 1 = 1
LCM(857,125) = ( 857 × 125 ) / 1
LCM(857,125) = 107125 / 1
LCM(857,125) = 107125
