Given numbers are 408,689,286,582,903
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 408,689,286,582,903 is 90283897704.
Find LCM of 408,689,286,582,903 with Prime Factorization
| 2 | 408, 689, 286, 582, 903 |
| 3 | 204, 689, 143, 291, 903 |
| 13 | 68, 689, 143, 97, 301 |
| 68, 53, 11, 97, 301 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 68 x 53 x 11 x 97 x 301 = 90283897704
Therefore, the lowest common multiple of 408,689,286,582,903 is 90283897704.
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.
408 x 689 x 286 x 582 x 903 = 42252864125472
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
689 : 1, 13, 53, 689
286 : 1, 2, 11, 13, 22, 26, 143, 286
582 : 1, 2, 3, 6, 97, 194, 291, 582
903 : 1, 3, 7, 21, 43, 129, 301, 903
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,689,286,582,903, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
689:13x 53
286:2x 11x 13
582:2x 3x 97
903:3x 7x 43
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 3x 3x 13 = 468
Therefore, the value for common factors is 468.
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 = 42252864125472/(1x468)
LCM = 42252864125472/468
LCM = 90283897704
Thus, we can understand that the LCM of 408,689,286,582,903 is 90283897704.
