Given numbers are 405,120,735,963,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,120,735,963,687 is 3890096280.
Find LCM of 405,120,735,963,687 with Prime Factorization
| 3 | 405, 120, 735, 963, 687 |
| 3 | 135, 40, 245, 321, 229 |
| 5 | 45, 40, 245, 107, 229 |
| 9, 8, 49, 107, 229 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 9 x 8 x 49 x 107 x 229 = 3890096280
Therefore, the lowest common multiple of 405,120,735,963,687 is 3890096280.
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.
405 x 120 x 735 x 963 x 687 = 23632334901000
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
963 : 1, 3, 9, 107, 321, 963
687 : 1, 3, 229, 687
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,120,735,963,687, is 3.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
120:2x 2x 2x 3x 5
735:3x 5x 7x 7
963:3x 3x 107
687:3x 229
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 3x 5x 5 = 2025
Therefore, the value for common factors is 2025.
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 = 23632334901000/(3x2025)
LCM = 23632334901000/6075
LCM = 3890096280
Thus, we can understand that the LCM of 405,120,735,963,687 is 3890096280.
