Given numbers are 834,921,432,558
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 834,921,432,558 is 571476816.
Find LCM of 834,921,432,558 with Prime Factorization
| 2 | 834, 921, 432, 558 |
| 3 | 417, 921, 216, 279 |
| 3 | 139, 307, 72, 93 |
| 139, 307, 24, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 139 x 307 x 24 x 31 = 571476816
Therefore, the lowest common multiple of 834,921,432,558 is 571476816.
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.
834 x 921 x 432 x 558 = 185158488384
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
921 : 1, 3, 307, 921
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,921,432,558, is 3.
Now, the common factors can be found like this.
834:2x 3x 139
921:3x 307
432:2x 2x 2x 2x 3x 3x 3
558:2x 3x 3x 31
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 3 = 108
Therefore, the value for common factors is 108.
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 = 185158488384/(3x108)
LCM = 185158488384/324
LCM = 571476816
Thus, we can understand that the LCM of 834,921,432,558 is 571476816.
