Given numbers are 705,633,864,449,353
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,633,864,449,353 is 6790239715680.
Find LCM of 705,633,864,449,353 with Prime Factorization
| 3 | 705, 633, 864, 449, 353 |
| 235, 211, 288, 449, 353 |
Multiply the prime numbers at the bottom and the left side.
3 x 235 x 211 x 288 x 449 x 353 = 6790239715680
Therefore, the lowest common multiple of 705,633,864,449,353 is 6790239715680.
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.
705 x 633 x 864 x 449 x 353 = 61112157441120
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
633 : 1, 3, 211, 633
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
449 : 1, 449
353 : 1, 353
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,633,864,449,353, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
633:3x 211
864:2x 2x 2x 2x 2x 3x 3x 3
449:449
353:353
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 61112157441120/(1x9)
LCM = 61112157441120/9
LCM = 6790239715680
Thus, we can understand that the LCM of 705,633,864,449,353 is 6790239715680.
