Find LCM of 384,407,880,689 with Prime Factorization
| 2 | 384, 407, 880, 689 |
| 2 | 192, 407, 440, 689 |
| 2 | 96, 407, 220, 689 |
| 2 | 48, 407, 110, 689 |
| 11 | 24, 407, 55, 689 |
| 24, 37, 5, 689 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 11 x 24 x 37 x 5 x 689 = 538412160
Therefore, the lowest common multiple of 384,407,880,689 is 538412160.
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.
384 x 407 x 880 x 689 = 94760540160
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.
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
407 : 1, 11, 37, 407
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 384,407,880,689, is 1.
Now, the common factors can be found like this.
384:2x 2x 2x 2x 2x 2x 2x 3
407:11x 37
880:2x 2x 2x 2x 5x 11
689:13x 53
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 11 = 176
Therefore, the value for common factors is 176.
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 = 94760540160/(1x176)
LCM = 94760540160/176
LCM = 538412160
Thus, we can understand that the LCM of 384,407,880,689 is 538412160.
