Given numbers are 884,923,143,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 884,923,143,638 is 20021716.
Find LCM of 884,923,143,638 with Prime Factorization
| 2 | 884, 923, 143, 638 |
| 11 | 442, 923, 143, 319 |
| 13 | 442, 923, 13, 29 |
| 34, 71, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 34 x 71 x 1 x 29 = 20021716
Therefore, the lowest common multiple of 884,923,143,638 is 20021716.
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.
884 x 923 x 143 x 638 = 74440740088
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.
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
923 : 1, 13, 71, 923
143 : 1, 11, 13, 143
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 884,923,143,638, is 1.
Now, the common factors can be found like this.
884:2x 2x 13x 17
923:13x 71
143:11x 13
638:2x 11x 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 11x 13x 13 = 3718
Therefore, the value for common factors is 3718.
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 = 74440740088/(1x3718)
LCM = 74440740088/3718
LCM = 20021716
Thus, we can understand that the LCM of 884,923,143,638 is 20021716.
