Given numbers are 864,587,382,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 864,587,382,663 is 21408068448.
Find LCM of 864,587,382,663 with Prime Factorization
| 2 | 864, 587, 382, 663 |
| 3 | 432, 587, 191, 663 |
| 144, 587, 191, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 144 x 587 x 191 x 221 = 21408068448
Therefore, the lowest common multiple of 864,587,382,663 is 21408068448.
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.
864 x 587 x 382 x 663 = 128448410688
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.
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
587 : 1, 587
382 : 1, 2, 191, 382
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,587,382,663, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
587:587
382:2x 191
663:3x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 128448410688/(1x6)
LCM = 128448410688/6
LCM = 21408068448
Thus, we can understand that the LCM of 864,587,382,663 is 21408068448.
