The factors of 170 are 1, 2, 5, 10, 17, 34, 85, 170
The factors of 122 are 1, 2, 61, 122
The HCF of 170,122 is 2.
Lets's calculate GCF of 170,122
2 | 170, 122 |
85, 61 |
∴ 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 122
:1,2,61,122
Greatest Common Factor
We found the factors 170,122 . The biggest common factor number is the GCF number.
So the greatest common factor 170,122 is 2.
Lets's calculate LCM of 348,305
Given numbers has no common factors except 1. So, there LCM is their product i.e 106140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/106140
Therefore, the GCF of Fractions 170/348,122/305 is 2/106140
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 348,305 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(348,305) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(348,305) x common factors =1 x 1 = 1
LCM(348,305) = ( 348 × 305 ) / 1
LCM(348,305) = 106140 / 1
LCM(348,305) = 106140
