Given numbers are 668,928,665,290,725
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,928,665,290,725 is 515295200.
Find LCM of 668,928,665,290,725 with Prime Factorization
| 2 | 668, 928, 665, 290, 725 |
| 2 | 334, 464, 665, 145, 725 |
| 5 | 167, 232, 665, 145, 725 |
| 29 | 167, 232, 133, 29, 145 |
| 167, 8, 133, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 29 x 167 x 8 x 133 x 1 x 5 = 515295200
Therefore, the lowest common multiple of 668,928,665,290,725 is 515295200.
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.
668 x 928 x 665 x 290 x 725 = 86672652640000
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.
668 : 1, 2, 4, 167, 334, 668
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
665 : 1, 5, 7, 19, 35, 95, 133, 665
290 : 1, 2, 5, 10, 29, 58, 145, 290
725 : 1, 5, 25, 29, 145, 725
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,928,665,290,725, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
928:2x 2x 2x 2x 2x 29
665:5x 7x 19
290:2x 5x 29
725:5x 5x 29
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 5x 5x 29x 29 = 168200
Therefore, the value for common factors is 168200.
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 = 86672652640000/(1x168200)
LCM = 86672652640000/168200
LCM = 515295200
Thus, we can understand that the LCM of 668,928,665,290,725 is 515295200.
