The HCF of 731,258 is 43.
Lets's calculate GCF of 731,258
43 | 731, 258 |
17, 6 |
∴ So the GCF of the given numbers is 43 = 43
Now, list down the factors of 731
:1,17,43,731
Now, list down the factors of 258
:1,2,3,6,43,86,129,258
Greatest Common Factor
We found the factors 731,258 . The biggest common factor number is the GCF number.
So the greatest common factor 731,258 is 43.
Lets's calculate LCM of 325,172
Given numbers has no common factors except 1. So, there LCM is their product i.e 55900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 43/55900
Therefore, the GCF of Fractions 731/325,258/172 is 43/55900
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 325,172 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(325,172) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(325,172) x common factors =1 x 1 = 1
LCM(325,172) = ( 325 × 172 ) / 1
LCM(325,172) = 55900 / 1
LCM(325,172) = 55900
