Given numbers are 489,616,946,671
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,616,946,671 is 790110552.
Find LCM of 489,616,946,671 with Prime Factorization
| 2 | 489, 616, 946, 671 |
| 11 | 489, 308, 473, 671 |
| 489, 28, 43, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 489 x 28 x 43 x 61 = 790110552
Therefore, the lowest common multiple of 489,616,946,671 is 790110552.
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 616 x 946 x 671 = 191206753584
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
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
946 : 1, 2, 11, 22, 43, 86, 473, 946
671 : 1, 11, 61, 671
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,616,946,671, is 1.
Now, the common factors can be found like this.
489:3x 163
616:2x 2x 2x 7x 11
946:2x 11x 43
671:11x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 191206753584/(1x242)
LCM = 191206753584/242
LCM = 790110552
Thus, we can understand that the LCM of 489,616,946,671 is 790110552.
