Find LCM of 105,629,391,620,867 with Prime Factorization
| 3 | 105, 629, 391, 620, 867 |
| 5 | 35, 629, 391, 620, 289 |
| 17 | 7, 629, 391, 124, 289 |
| 7, 37, 23, 124, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 7 x 37 x 23 x 124 x 17 = 3202125780
Therefore, the lowest common multiple of 105,629,391,620,867 is 3202125780.
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.
105 x 629 x 391 x 620 x 867 = 13881215256300
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
629 : 1, 17, 37, 629
391 : 1, 17, 23, 391
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
867 : 1, 3, 17, 51, 289, 867
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,629,391,620,867, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
629:17x 37
391:17x 23
620:2x 2x 5x 31
867:3x 17x 17
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 17x 17 = 4335
Therefore, the value for common factors is 4335.
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 = 13881215256300/(1x4335)
LCM = 13881215256300/4335
LCM = 3202125780
Thus, we can understand that the LCM of 105,629,391,620,867 is 3202125780.
