The factors of 206 are 1, 2, 103, 206
The HCF of 458,206 is 2.
Lets's calculate GCF of 458,206
2 | 458, 206 |
229, 103 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 458
:1,2,229,458
Now, list down the factors of 206
:1,2,103,206
Greatest Common Factor
We found the factors 458,206 . The biggest common factor number is the GCF number.
So the greatest common factor 458,206 is 2.
Lets's calculate LCM of 251,140
Given numbers has no common factors except 1. So, there LCM is their product i.e 35140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/35140
Therefore, the GCF of Fractions 458/251,206/140 is 2/35140
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 251,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(251,140) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(251,140) x common factors =1 x 1 = 1
LCM(251,140) = ( 251 × 140 ) / 1
LCM(251,140) = 35140 / 1
LCM(251,140) = 35140
