Given numbers are 723,840,384,473
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,840,384,473 is 1532065920.
Find LCM of 723,840,384,473 with Prime Factorization
| 2 | 723, 840, 384, 473 |
| 2 | 723, 420, 192, 473 |
| 2 | 723, 210, 96, 473 |
| 3 | 723, 105, 48, 473 |
| 241, 35, 16, 473 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 241 x 35 x 16 x 473 = 1532065920
Therefore, the lowest common multiple of 723,840,384,473 is 1532065920.
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.
723 x 840 x 384 x 473 = 110308746240
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.
723 : 1, 3, 241, 723
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
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
473 : 1, 11, 43, 473
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,840,384,473, is 1.
Now, the common factors can be found like this.
723:3x 241
840:2x 2x 2x 3x 5x 7
384:2x 2x 2x 2x 2x 2x 2x 3
473:11x 43
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 110308746240/(1x72)
LCM = 110308746240/72
LCM = 1532065920
Thus, we can understand that the LCM of 723,840,384,473 is 1532065920.
