Find LCM of 105,518,128,872,489 with Prime Factorization
| 2 | 105, 518, 128, 872, 489 |
| 2 | 105, 259, 64, 436, 489 |
| 2 | 105, 259, 32, 218, 489 |
| 3 | 105, 259, 16, 109, 489 |
| 7 | 35, 259, 16, 109, 163 |
| 5, 37, 16, 109, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 5 x 37 x 16 x 109 x 163 = 8835173760
Therefore, the lowest common multiple of 105,518,128,872,489 is 8835173760.
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 518 x 128 x 872 x 489 = 2968618383360
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
518 : 1, 2, 7, 14, 37, 74, 259, 518
128 : 1, 2, 4, 8, 16, 32, 64, 128
872 : 1, 2, 4, 8, 109, 218, 436, 872
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,518,128,872,489, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
518:2x 7x 37
128:2x 2x 2x 2x 2x 2x 2
872:2x 2x 2x 109
489:3x 163
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 2x 2x 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 2968618383360/(1x336)
LCM = 2968618383360/336
LCM = 8835173760
Thus, we can understand that the LCM of 105,518,128,872,489 is 8835173760.
