Given numbers are 803,391,817,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 803,391,817,418 is 513031882.
Find LCM of 803,391,817,418 with Prime Factorization
11 | 803, 391, 817, 418 |
19 | 73, 391, 817, 38 |
73, 391, 43, 2 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 73 x 391 x 43 x 2 = 513031882
Therefore, the lowest common multiple of 803,391,817,418 is 513031882.
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.
803 x 391 x 817 x 418 = 107223663338
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.
803 : 1, 11, 73, 803
391 : 1, 17, 23, 391
817 : 1, 19, 43, 817
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,391,817,418, is 1.
Now, the common factors can be found like this.
803:11x 73
391:17x 23
817:19x 43
418:2x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 19 = 209
Therefore, the value for common factors is 209.
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 = 107223663338/(1x209)
LCM = 107223663338/209
LCM = 513031882
Thus, we can understand that the LCM of 803,391,817,418 is 513031882.
