Given numbers are 489,490,934,424
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,490,934,424 is 23722348440.
Find LCM of 489,490,934,424 with Prime Factorization
| 2 | 489, 490, 934, 424 |
| 489, 245, 467, 212 |
Multiply the prime numbers at the bottom and the left side.
2 x 489 x 245 x 467 x 212 = 23722348440
Therefore, the lowest common multiple of 489,490,934,424 is 23722348440.
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 490 x 934 x 424 = 94889393760
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
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
934 : 1, 2, 467, 934
424 : 1, 2, 4, 8, 53, 106, 212, 424
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,490,934,424, is 1.
Now, the common factors can be found like this.
489:3x 163
490:2x 5x 7x 7
934:2x 467
424:2x 2x 2x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 94889393760/(1x4)
LCM = 94889393760/4
LCM = 23722348440
Thus, we can understand that the LCM of 489,490,934,424 is 23722348440.
