Given numbers are 423,330,979,660,123
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,330,979,660,123 is 339575940.
Find LCM of 423,330,979,660,123 with Prime Factorization
| 2 | 423, 330, 979, 660, 123 |
| 3 | 423, 165, 979, 330, 123 |
| 5 | 141, 55, 979, 110, 41 |
| 11 | 141, 11, 979, 22, 41 |
| 141, 1, 89, 2, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 141 x 1 x 89 x 2 x 41 = 339575940
Therefore, the lowest common multiple of 423,330,979,660,123 is 339575940.
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 330 x 979 x 660 x 123 = 11093945959800
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
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
979 : 1, 11, 89, 979
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,330,979,660,123, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
330:2x 3x 5x 11
979:11x 89
660:2x 2x 3x 5x 11
123:3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 11x 11 = 32670
Therefore, the value for common factors is 32670.
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 = 11093945959800/(1x32670)
LCM = 11093945959800/32670
LCM = 339575940
Thus, we can understand that the LCM of 423,330,979,660,123 is 339575940.
