Lets's calculate GCF of 438,681
3 | 438, 681 |
146, 227 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 438
:1,2,3,6,73,146,219,438
Now, list down the factors of 681
:1,3,227,681
Greatest Common Factor
We found the factors 438,681 . The biggest common factor number is the GCF number.
So the greatest common factor 438,681 is 3.
Lets's calculate LCM of 449,423
Given numbers has no common factors except 1. So, there LCM is their product i.e 189927
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/189927
Therefore, the GCF of Fractions 438/449,681/423 is 3/189927
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 449,423 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(449,423) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(449,423) x common factors =1 x 1 = 1
LCM(449,423) = ( 449 × 423 ) / 1
LCM(449,423) = 189927 / 1
LCM(449,423) = 189927
