Given numbers are 538,135,732,568,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,135,732,568,390 is 16357147560.
Find LCM of 538,135,732,568,390 with Prime Factorization
| 2 | 538, 135, 732, 568, 390 |
| 2 | 269, 135, 366, 284, 195 |
| 3 | 269, 135, 183, 142, 195 |
| 5 | 269, 45, 61, 142, 65 |
| 269, 9, 61, 142, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 269 x 9 x 61 x 142 x 13 = 16357147560
Therefore, the lowest common multiple of 538,135,732,568,390 is 16357147560.
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.
538 x 135 x 732 x 568 x 390 = 11777146243200
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.
538 : 1, 2, 269, 538
135 : 1, 3, 5, 9, 15, 27, 45, 135
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
568 : 1, 2, 4, 8, 71, 142, 284, 568
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,135,732,568,390, is 1.
Now, the common factors can be found like this.
538:2x 269
135:3x 3x 3x 5
732:2x 2x 3x 61
568:2x 2x 2x 71
390:2x 3x 5x 13
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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 11777146243200/(1x720)
LCM = 11777146243200/720
LCM = 16357147560
Thus, we can understand that the LCM of 538,135,732,568,390 is 16357147560.
