Given numbers are 489,428,107,135
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,428,107,135 is 9418140.
Find LCM of 489,428,107,135 with Prime Factorization
| 3 | 489, 428, 107, 135 |
| 107 | 163, 428, 107, 45 |
| 163, 4, 1, 45 |
Multiply the prime numbers at the bottom and the left side.
3 x 107 x 163 x 4 x 1 x 45 = 9418140
Therefore, the lowest common multiple of 489,428,107,135 is 9418140.
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.
489 x 428 x 107 x 135 = 3023222940
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.
489 : 1, 3, 163, 489
428 : 1, 2, 4, 107, 214, 428
107 : 1, 107
135 : 1, 3, 5, 9, 15, 27, 45, 135
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,428,107,135, is 1.
Now, the common factors can be found like this.
489:3x 163
428:2x 2x 107
107:107
135:3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 107 = 321
Therefore, the value for common factors is 321.
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 = 3023222940/(1x321)
LCM = 3023222940/321
LCM = 9418140
Thus, we can understand that the LCM of 489,428,107,135 is 9418140.
