Given numbers are 489,369,896,690,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,369,896,690,918 is 316074890880.
Find LCM of 489,369,896,690,918 with Prime Factorization
| 2 | 489, 369, 896, 690, 918 |
| 3 | 489, 369, 448, 345, 459 |
| 3 | 163, 123, 448, 115, 153 |
| 163, 41, 448, 115, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 163 x 41 x 448 x 115 x 51 = 316074890880
Therefore, the lowest common multiple of 489,369,896,690,918 is 316074890880.
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.
489 x 369 x 896 x 690 x 918 = 102408264645120
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.
489 : 1, 3, 163, 489
369 : 1, 3, 9, 41, 123, 369
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,369,896,690,918, is 1.
Now, the common factors can be found like this.
489:3x 163
369:3x 3x 41
896:2x 2x 2x 2x 2x 2x 2x 7
690:2x 3x 5x 23
918:2x 3x 3x 3x 17
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 = 102408264645120/(1x324)
LCM = 102408264645120/324
LCM = 316074890880
Thus, we can understand that the LCM of 489,369,896,690,918 is 316074890880.
