Given numbers are 156,856,797,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 156,856,797,447 is 3964450152.
Find LCM of 156,856,797,447 with Prime Factorization
| 2 | 156, 856, 797, 447 |
| 2 | 78, 428, 797, 447 |
| 3 | 39, 214, 797, 447 |
| 13, 214, 797, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 214 x 797 x 149 = 3964450152
Therefore, the lowest common multiple of 156,856,797,447 is 3964450152.
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.
156 x 856 x 797 x 447 = 47573401824
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
856 : 1, 2, 4, 8, 107, 214, 428, 856
797 : 1, 797
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,856,797,447, is 1.
Now, the common factors can be found like this.
156:2x 2x 3x 13
856:2x 2x 2x 107
797:797
447:3x 149
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 3 = 12
Therefore, the value for common factors is 12.
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 = 47573401824/(1x12)
LCM = 47573401824/12
LCM = 3964450152
Thus, we can understand that the LCM of 156,856,797,447 is 3964450152.
