Given numbers are 298,436,418,209,838
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 298,436,418,209,838 is 5688962444.
Find LCM of 298,436,418,209,838 with Prime Factorization
| 2 | 298, 436, 418, 209, 838 |
| 11 | 149, 218, 209, 209, 419 |
| 19 | 149, 218, 19, 19, 419 |
| 149, 218, 1, 1, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 149 x 218 x 1 x 1 x 419 = 5688962444
Therefore, the lowest common multiple of 298,436,418,209,838 is 5688962444.
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.
298 x 436 x 418 x 209 x 838 = 9511945206368
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.
298 : 1, 2, 149, 298
436 : 1, 2, 4, 109, 218, 436
418 : 1, 2, 11, 19, 22, 38, 209, 418
209 : 1, 11, 19, 209
838 : 1, 2, 419, 838
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,436,418,209,838, is 1.
Now, the common factors can be found like this.
298:2x 149
436:2x 2x 109
418:2x 11x 19
209:11x 19
838:2x 419
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 11x 19 = 1672
Therefore, the value for common factors is 1672.
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 = 9511945206368/(1x1672)
LCM = 9511945206368/1672
LCM = 5688962444
Thus, we can understand that the LCM of 298,436,418,209,838 is 5688962444.
