To find the highest common factor of 721,406, we have to find the factors of both numbers and list the highest common factor.
The factors of 721 are 1, 7, 103, 721
The factors of 406 are 1, 2, 7, 14, 29, 58, 203, 406
The HCF of 721,406 is 7.
Lets's calculate GCF of 721,406
7 | 721, 406 |
103, 58 |
∴ So the GCF of the given numbers is 7 = 7
Now, list down the factors of 721
:1,7,103,721
Now, list down the factors of 406
:1,2,7,14,29,58,203,406
Greatest Common Factor
We found the factors 721,406 . The biggest common factor number is the GCF number.
So the greatest common factor 721,406 is 7.
Lets's calculate LCM of 194,305
Given numbers has no common factors except 1. So, there LCM is their product i.e 59170
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/59170
Therefore, the GCF of Fractions 721/194,406/305 is 7/59170
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 194,305 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(194,305) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(194,305) x common factors =1 x 1 = 1
LCM(194,305) = ( 194 × 305 ) / 1
LCM(194,305) = 59170 / 1
LCM(194,305) = 59170
