Given numbers are 409,815,225,369
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,815,225,369 is 615003075.
Find LCM of 409,815,225,369 with Prime Factorization
| 3 | 409, 815, 225, 369 |
| 3 | 409, 815, 75, 123 |
| 5 | 409, 815, 25, 41 |
| 409, 163, 5, 41 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 409 x 163 x 5 x 41 = 615003075
Therefore, the lowest common multiple of 409,815,225,369 is 615003075.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
409 x 815 x 225 x 369 = 27675138375
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
409 : 1, 409
815 : 1, 5, 163, 815
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
369 : 1, 3, 9, 41, 123, 369
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,815,225,369, is 1.
Now, the common factors can be found like this.
409:409
815:5x 163
225:3x 3x 5x 5
369:3x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 27675138375/(1x45)
LCM = 27675138375/45
LCM = 615003075
Thus, we can understand that the LCM of 409,815,225,369 is 615003075.
