Given numbers are 423,108,218,558
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,108,218,558 is 17151804.
Find LCM of 423,108,218,558 with Prime Factorization
| 2 | 423, 108, 218, 558 |
| 3 | 423, 54, 109, 279 |
| 3 | 141, 18, 109, 93 |
| 47, 6, 109, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 47 x 6 x 109 x 31 = 17151804
Therefore, the lowest common multiple of 423,108,218,558 is 17151804.
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.
423 x 108 x 218 x 558 = 5557184496
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.
423 : 1, 3, 9, 47, 141, 423
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
218 : 1, 2, 109, 218
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,108,218,558, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
108:2x 2x 3x 3x 3
218:2x 109
558:2x 3x 3x 31
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 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 5557184496/(1x324)
LCM = 5557184496/324
LCM = 17151804
Thus, we can understand that the LCM of 423,108,218,558 is 17151804.
