Given numbers are 299,575,715,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 299,575,715,768 is 63148800.
Find LCM of 299,575,715,768 with Prime Factorization
| 5 | 299, 575, 715, 768 |
| 13 | 299, 115, 143, 768 |
| 23 | 23, 115, 11, 768 |
| 1, 5, 11, 768 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 23 x 1 x 5 x 11 x 768 = 63148800
Therefore, the lowest common multiple of 299,575,715,768 is 63148800.
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.
299 x 575 x 715 x 768 = 94407456000
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.
299 : 1, 13, 23, 299
575 : 1, 5, 23, 25, 115, 575
715 : 1, 5, 11, 13, 55, 65, 143, 715
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 299,575,715,768, is 1.
Now, the common factors can be found like this.
299:13x 23
575:5x 5x 23
715:5x 11x 13
768:2x 2x 2x 2x 2x 2x 2x 2x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13x 23 = 1495
Therefore, the value for common factors is 1495.
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 = 94407456000/(1x1495)
LCM = 94407456000/1495
LCM = 63148800
Thus, we can understand that the LCM of 299,575,715,768 is 63148800.
