Given numbers are 418,715,319,874
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,715,319,874 is 18122390.
Find LCM of 418,715,319,874 with Prime Factorization
| 2 | 418, 715, 319, 874 |
| 11 | 209, 715, 319, 437 |
| 19 | 19, 65, 29, 437 |
| 1, 65, 29, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 1 x 65 x 29 x 23 = 18122390
Therefore, the lowest common multiple of 418,715,319,874 is 18122390.
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.
418 x 715 x 319 x 874 = 83326749220
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
715 : 1, 5, 11, 13, 55, 65, 143, 715
319 : 1, 11, 29, 319
874 : 1, 2, 19, 23, 38, 46, 437, 874
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,715,319,874, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
715:5x 11x 13
319:11x 29
874:2x 19x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 19 = 4598
Therefore, the value for common factors is 4598.
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 = 83326749220/(1x4598)
LCM = 83326749220/4598
LCM = 18122390
Thus, we can understand that the LCM of 418,715,319,874 is 18122390.
