Given numbers are 184,420,736,872,838
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 184,420,736,872,838 is 3529454880.
Find LCM of 184,420,736,872,838 with Prime Factorization
| 2 | 184, 420, 736, 872, 838 |
| 2 | 92, 210, 368, 436, 419 |
| 2 | 46, 105, 184, 218, 419 |
| 23 | 23, 105, 92, 109, 419 |
| 1, 105, 4, 109, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 23 x 1 x 105 x 4 x 109 x 419 = 3529454880
Therefore, the lowest common multiple of 184,420,736,872,838 is 3529454880.
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.
184 x 420 x 736 x 872 x 838 = 41562860666880
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.
184 : 1, 2, 4, 8, 23, 46, 92, 184
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
872 : 1, 2, 4, 8, 109, 218, 436, 872
838 : 1, 2, 419, 838
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 184,420,736,872,838, is 2.
Now, the common factors can be found like this.
184:2x 2x 2x 23
420:2x 2x 3x 5x 7
736:2x 2x 2x 2x 2x 23
872:2x 2x 2x 109
838:2x 419
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 2x 2x 2x 23 = 5888
Therefore, the value for common factors is 5888.
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 = 41562860666880/(2x5888)
LCM = 41562860666880/11776
LCM = 3529454880
Thus, we can understand that the LCM of 184,420,736,872,838 is 3529454880.
