Given numbers are 759,405,330,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 759,405,330,981 is 22337370.
Find LCM of 759,405,330,981 with Prime Factorization
| 3 | 759, 405, 330, 981 |
| 3 | 253, 135, 110, 327 |
| 5 | 253, 45, 110, 109 |
| 11 | 253, 9, 22, 109 |
| 23, 9, 2, 109 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 11 x 23 x 9 x 2 x 109 = 22337370
Therefore, the lowest common multiple of 759,405,330,981 is 22337370.
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.
759 x 405 x 330 x 981 = 99512983350
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.
759 : 1, 3, 11, 23, 33, 69, 253, 759
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
981 : 1, 3, 9, 109, 327, 981
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 759,405,330,981, is 3.
Now, the common factors can be found like this.
759:3x 11x 23
405:3x 3x 3x 3x 5
330:2x 3x 5x 11
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 11 = 1485
Therefore, the value for common factors is 1485.
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 = 99512983350/(3x1485)
LCM = 99512983350/4455
LCM = 22337370
Thus, we can understand that the LCM of 759,405,330,981 is 22337370.
