Given numbers are 818,323,642,437,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 818,323,642,437,870 is 282850334490.
Find LCM of 818,323,642,437,870 with Prime Factorization
| 2 | 818, 323, 642, 437, 870 |
| 3 | 409, 323, 321, 437, 435 |
| 19 | 409, 323, 107, 437, 145 |
| 409, 17, 107, 23, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 409 x 17 x 107 x 23 x 145 = 282850334490
Therefore, the lowest common multiple of 818,323,642,437,870 is 282850334490.
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.
818 x 323 x 642 x 437 x 870 = 64489876263720
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.
818 : 1, 2, 409, 818
323 : 1, 17, 19, 323
642 : 1, 2, 3, 6, 107, 214, 321, 642
437 : 1, 19, 23, 437
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,323,642,437,870, is 1.
Now, the common factors can be found like this.
818:2x 409
323:17x 19
642:2x 3x 107
437:19x 23
870:2x 3x 5x 29
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 19 = 228
Therefore, the value for common factors is 228.
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 = 64489876263720/(1x228)
LCM = 64489876263720/228
LCM = 282850334490
Thus, we can understand that the LCM of 818,323,642,437,870 is 282850334490.
