Given numbers are 326,800,436,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 326,800,436,840 is 298485600.
Find LCM of 326,800,436,840 with Prime Factorization
| 2 | 326, 800, 436, 840 |
| 2 | 163, 400, 218, 420 |
| 2 | 163, 200, 109, 210 |
| 5 | 163, 100, 109, 105 |
| 163, 20, 109, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 163 x 20 x 109 x 21 = 298485600
Therefore, the lowest common multiple of 326,800,436,840 is 298485600.
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.
326 x 800 x 436 x 840 = 95515392000
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.
326 : 1, 2, 163, 326
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
436 : 1, 2, 4, 109, 218, 436
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,800,436,840, is 2.
Now, the common factors can be found like this.
326:2x 163
800:2x 2x 2x 2x 2x 5x 5
436:2x 2x 109
840:2x 2x 2x 3x 5x 7
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 5 = 160
Therefore, the value for common factors is 160.
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 = 95515392000/(2x160)
LCM = 95515392000/320
LCM = 298485600
Thus, we can understand that the LCM of 326,800,436,840 is 298485600.
