Given numbers are 810,561,286,374
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 810,561,286,374 is 1969110.
Find LCM of 810,561,286,374 with Prime Factorization
| 2 | 810, 561, 286, 374 |
| 3 | 405, 561, 143, 187 |
| 11 | 135, 187, 143, 187 |
| 17 | 135, 17, 13, 17 |
| 135, 1, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 135 x 1 x 13 x 1 = 1969110
Therefore, the lowest common multiple of 810,561,286,374 is 1969110.
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.
810 x 561 x 286 x 374 = 48605511240
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
561 : 1, 3, 11, 17, 33, 51, 187, 561
286 : 1, 2, 11, 13, 22, 26, 143, 286
374 : 1, 2, 11, 17, 22, 34, 187, 374
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,561,286,374, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
561:3x 11x 17
286:2x 11x 13
374:2x 11x 17
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 11x 11x 17 = 24684
Therefore, the value for common factors is 24684.
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 = 48605511240/(1x24684)
LCM = 48605511240/24684
LCM = 1969110
Thus, we can understand that the LCM of 810,561,286,374 is 1969110.
