Given numbers are 804,408,520,665
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 804,408,520,665 is 236319720.
Find LCM of 804,408,520,665 with Prime Factorization
| 2 | 804, 408, 520, 665 |
| 2 | 402, 204, 260, 665 |
| 2 | 201, 102, 130, 665 |
| 3 | 201, 51, 65, 665 |
| 5 | 67, 17, 65, 665 |
| 67, 17, 13, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 67 x 17 x 13 x 133 = 236319720
Therefore, the lowest common multiple of 804,408,520,665 is 236319720.
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.
804 x 408 x 520 x 665 = 113433465600
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.
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,408,520,665, is 1.
Now, the common factors can be found like this.
804:2x 2x 3x 67
408:2x 2x 2x 3x 17
520:2x 2x 2x 5x 13
665:5x 7x 19
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 2x 3x 5 = 480
Therefore, the value for common factors is 480.
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 = 113433465600/(1x480)
LCM = 113433465600/480
LCM = 236319720
Thus, we can understand that the LCM of 804,408,520,665 is 236319720.
