Given numbers are 805,407,786,206,515
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,407,786,206,515 is 26524674330.
Find LCM of 805,407,786,206,515 with Prime Factorization
| 2 | 805, 407, 786, 206, 515 |
| 5 | 805, 407, 393, 103, 515 |
| 103 | 161, 407, 393, 103, 103 |
| 161, 407, 393, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 103 x 161 x 407 x 393 x 1 x 1 = 26524674330
Therefore, the lowest common multiple of 805,407,786,206,515 is 26524674330.
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 407 x 786 x 206 x 515 = 27320414559900
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
407 : 1, 11, 37, 407
786 : 1, 2, 3, 6, 131, 262, 393, 786
206 : 1, 2, 103, 206
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,407,786,206,515, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
407:11x 37
786:2x 3x 131
206:2x 103
515:5x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 103 = 1030
Therefore, the value for common factors is 1030.
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 = 27320414559900/(1x1030)
LCM = 27320414559900/1030
LCM = 26524674330
Thus, we can understand that the LCM of 805,407,786,206,515 is 26524674330.
