The LCM of 403,884,815,620,818 is 9134712340.
Find LCM of 403,884,815,620,818 with Prime Factorization
| 2 | 403, 884, 815, 620, 818 |
| 2 | 403, 442, 815, 310, 409 |
| 5 | 403, 221, 815, 155, 409 |
| 13 | 403, 221, 163, 31, 409 |
| 31 | 31, 17, 163, 31, 409 |
| 1, 17, 163, 1, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 31 x 1 x 17 x 163 x 1 x 409 = 9134712340
Therefore, the lowest common multiple of 403,884,815,620,818 is 9134712340.
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.
403 x 884 x 815 x 620 x 818 = 147251562920800
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.
403 : 1, 13, 31, 403
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
815 : 1, 5, 163, 815
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
818 : 1, 2, 409, 818
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,884,815,620,818, is 1.
Now, the common factors can be found like this.
403:13x 31
884:2x 2x 13x 17
815:5x 163
620:2x 2x 5x 31
818:2x 409
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 5x 13x 31 = 16120
Therefore, the value for common factors is 16120.
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 = 147251562920800/(1x16120)
LCM = 147251562920800/16120
LCM = 9134712340
Thus, we can understand that the LCM of 403,884,815,620,818 is 9134712340.
