Given numbers are 805,667,891,406,355
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,667,891,406,355 is 2953656090.
Find LCM of 805,667,891,406,355 with Prime Factorization
| 5 | 805, 667, 891, 406, 355 |
| 7 | 161, 667, 891, 406, 71 |
| 23 | 23, 667, 891, 58, 71 |
| 29 | 1, 29, 891, 58, 71 |
| 1, 1, 891, 2, 71 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 23 x 29 x 1 x 1 x 891 x 2 x 71 = 2953656090
Therefore, the lowest common multiple of 805,667,891,406,355 is 2953656090.
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.
805 x 667 x 891 x 406 x 355 = 68953101421050
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
667 : 1, 23, 29, 667
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
406 : 1, 2, 7, 14, 29, 58, 203, 406
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,667,891,406,355, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
667:23x 29
891:3x 3x 3x 3x 11
406:2x 7x 29
355:5x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 23x 29 = 23345
Therefore, the value for common factors is 23345.
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 = 68953101421050/(1x23345)
LCM = 68953101421050/23345
LCM = 2953656090
Thus, we can understand that the LCM of 805,667,891,406,355 is 2953656090.
