Given numbers are 855,487,510,396
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,487,510,396 is 311455980.
Find LCM of 855,487,510,396 with Prime Factorization
| 2 | 855, 487, 510, 396 |
| 3 | 855, 487, 255, 198 |
| 3 | 285, 487, 85, 66 |
| 5 | 95, 487, 85, 22 |
| 19, 487, 17, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 19 x 487 x 17 x 22 = 311455980
Therefore, the lowest common multiple of 855,487,510,396 is 311455980.
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.
855 x 487 x 510 x 396 = 84093114600
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
487 : 1, 487
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,487,510,396, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
487:487
510:2x 3x 5x 17
396:2x 2x 3x 3x 11
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 5 = 270
Therefore, the value for common factors is 270.
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 = 84093114600/(1x270)
LCM = 84093114600/270
LCM = 311455980
Thus, we can understand that the LCM of 855,487,510,396 is 311455980.
