Given numbers are 207,870,815,667
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 207,870,815,667 is 9784890.
Find LCM of 207,870,815,667 with Prime Factorization
| 3 | 207, 870, 815, 667 |
| 5 | 69, 290, 815, 667 |
| 23 | 69, 58, 163, 667 |
| 29 | 3, 58, 163, 29 |
| 3, 2, 163, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 29 x 3 x 2 x 163 x 1 = 9784890
Therefore, the lowest common multiple of 207,870,815,667 is 9784890.
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.
207 x 870 x 815 x 667 = 97897824450
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.
207 : 1, 3, 9, 23, 69, 207
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
815 : 1, 5, 163, 815
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,870,815,667, is 1.
Now, the common factors can be found like this.
207:3x 3x 23
870:2x 3x 5x 29
815:5x 163
667:23x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 23x 29 = 10005
Therefore, the value for common factors is 10005.
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 = 97897824450/(1x10005)
LCM = 97897824450/10005
LCM = 9784890
Thus, we can understand that the LCM of 207,870,815,667 is 9784890.
