The LCM of 432,840,676,481 is 94545360.
Find LCM of 432,840,676,481 with Prime Factorization
| 2 | 432, 840, 676, 481 |
| 2 | 216, 420, 338, 481 |
| 2 | 108, 210, 169, 481 |
| 3 | 54, 105, 169, 481 |
| 13 | 18, 35, 169, 481 |
| 18, 35, 13, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 18 x 35 x 13 x 37 = 94545360
Therefore, the lowest common multiple of 432,840,676,481 is 94545360.
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.
432 x 840 x 676 x 481 = 117992609280
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.
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
481 : 1, 13, 37, 481
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,840,676,481, is 1.
Now, the common factors can be found like this.
432:2x 2x 2x 2x 3x 3x 3
840:2x 2x 2x 3x 5x 7
676:2x 2x 13x 13
481:13x 37
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 2x 3x 13 = 1248
Therefore, the value for common factors is 1248.
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 = 117992609280/(1x1248)
LCM = 117992609280/1248
LCM = 94545360
Thus, we can understand that the LCM of 432,840,676,481 is 94545360.
