Given numbers are 621,813,684,718,762
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,813,684,718,762 is 583139758788.
Find LCM of 621,813,684,718,762 with Prime Factorization
| 2 | 621, 813, 684, 718, 762 |
| 3 | 621, 813, 342, 359, 381 |
| 3 | 207, 271, 114, 359, 127 |
| 69, 271, 38, 359, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 69 x 271 x 38 x 359 x 127 = 583139758788
Therefore, the lowest common multiple of 621,813,684,718,762 is 583139758788.
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.
621 x 813 x 684 x 718 x 762 = 188937281847312
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
813 : 1, 3, 271, 813
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
718 : 1, 2, 359, 718
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,813,684,718,762, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
813:3x 271
684:2x 2x 3x 3x 19
718:2x 359
762:2x 3x 127
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 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 188937281847312/(1x324)
LCM = 188937281847312/324
LCM = 583139758788
Thus, we can understand that the LCM of 621,813,684,718,762 is 583139758788.
