Given numbers are 845,894,886,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,894,886,728 is 9370353720.
Find LCM of 845,894,886,728 with Prime Factorization
| 2 | 845, 894, 886, 728 |
| 13 | 845, 447, 443, 364 |
| 65, 447, 443, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 65 x 447 x 443 x 28 = 9370353720
Therefore, the lowest common multiple of 845,894,886,728 is 9370353720.
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.
845 x 894 x 886 x 728 = 487258393440
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.
845 : 1, 5, 13, 65, 169, 845
894 : 1, 2, 3, 6, 149, 298, 447, 894
886 : 1, 2, 443, 886
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,894,886,728, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
894:2x 3x 149
886:2x 443
728:2x 2x 2x 7x 13
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 13 = 52
Therefore, the value for common factors is 52.
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 = 487258393440/(1x52)
LCM = 487258393440/52
LCM = 9370353720
Thus, we can understand that the LCM of 845,894,886,728 is 9370353720.
