Given numbers are 489,823,838,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,823,838,748 is 126131719164.
Find LCM of 489,823,838,748 with Prime Factorization
| 2 | 489, 823, 838, 748 |
| 489, 823, 419, 374 |
Multiply the prime numbers at the bottom and the left side.
2 x 489 x 823 x 419 x 374 = 126131719164
Therefore, the lowest common multiple of 489,823,838,748 is 126131719164.
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 823 x 838 x 748 = 252263438328
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
823 : 1, 823
838 : 1, 2, 419, 838
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,823,838,748, is 1.
Now, the common factors can be found like this.
489:3x 163
823:823
838:2x 419
748:2x 2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 252263438328/(1x2)
LCM = 252263438328/2
LCM = 126131719164
Thus, we can understand that the LCM of 489,823,838,748 is 126131719164.
