The factors of 404 are 1, 2, 4, 101, 202, 404
The HCF of 248,404 is 4.
Lets's calculate GCF of 248,404
2 | 248, 404 |
2 | 124, 202 |
62, 101 |
∴ So the GCF of the given numbers is 2 x 2 = 4
Now, list down the factors of 248
:1,2,4,8,31,62,124,248
Now, list down the factors of 404
:1,2,4,101,202,404
Greatest Common Factor
We found the factors 248,404 . The biggest common factor number is the GCF number.
So the greatest common factor 248,404 is 4.
Lets's calculate LCM of 387,517
Given numbers has no common factors except 1. So, there LCM is their product i.e 200079
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/200079
Therefore, the GCF of Fractions 248/387,404/517 is 4/200079
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 387,517 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(387,517) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(387,517) x common factors =1 x 1 = 1
LCM(387,517) = ( 387 × 517 ) / 1
LCM(387,517) = 200079 / 1
LCM(387,517) = 200079
