To find the highest common factor of 170,346, we have to find the factors of both numbers and list the highest common factor.
The factors of 170 are 1, 2, 5, 10, 17, 34, 85, 170
The factors of 346 are 1, 2, 173, 346
The HCF of 170,346 is 2.
Lets's calculate GCF of 170,346
2 | 170, 346 |
85, 173 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 170
:1,2,5,10,17,34,85,170
Now, list down the factors of 346
:1,2,173,346
Greatest Common Factor
We found the factors 170,346 . The biggest common factor number is the GCF number.
So the greatest common factor 170,346 is 2.
Lets's calculate LCM of 40,170
2 | 40, 170 |
5 | 20, 85 |
4, 17 |
∴ So the LCM of the given numbers is 2 x 5 x 4 x 17 = 680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/680
Therefore, the GCF of Fractions 170/40,346/170 is 2/680
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 40,170 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,170) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(40,170) x common factors =10 x 1 = 10
LCM(40,170) = ( 40 × 170 ) / 10
LCM(40,170) = 6800 / 10
LCM(40,170) = 680
