Given numbers are 846,855,578,834
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 846,855,578,834 is 3228543270.
Find LCM of 846,855,578,834 with Prime Factorization
| 2 | 846, 855, 578, 834 |
| 3 | 423, 855, 289, 417 |
| 3 | 141, 285, 289, 139 |
| 47, 95, 289, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 47 x 95 x 289 x 139 = 3228543270
Therefore, the lowest common multiple of 846,855,578,834 is 3228543270.
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.
846 x 855 x 578 x 834 = 348682673160
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.
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
578 : 1, 2, 17, 34, 289, 578
834 : 1, 2, 3, 6, 139, 278, 417, 834
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 846,855,578,834, is 1.
Now, the common factors can be found like this.
846:2x 3x 3x 47
855:3x 3x 5x 19
578:2x 17x 17
834:2x 3x 139
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 = 348682673160/(1x108)
LCM = 348682673160/108
LCM = 3228543270
Thus, we can understand that the LCM of 846,855,578,834 is 3228543270.
