Given numbers are 455,715,806,260
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,715,806,260 is 620620.
Find LCM of 455,715,806,260 with Prime Factorization
| 2 | 455, 715, 806, 260 |
| 5 | 455, 715, 403, 130 |
| 13 | 91, 143, 403, 26 |
| 7, 11, 31, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 7 x 11 x 31 x 2 = 620620
Therefore, the lowest common multiple of 455,715,806,260 is 620620.
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.
455 x 715 x 806 x 260 = 68175107000
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
715 : 1, 5, 11, 13, 55, 65, 143, 715
806 : 1, 2, 13, 26, 31, 62, 403, 806
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,715,806,260, is 13.
Now, the common factors can be found like this.
455:5x 7x 13
715:5x 11x 13
806:2x 13x 31
260:2x 2x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 13x 13 = 8450
Therefore, the value for common factors is 8450.
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 = 68175107000/(13x8450)
LCM = 68175107000/109850
LCM = 620620
Thus, we can understand that the LCM of 455,715,806,260 is 620620.
