Given numbers are 893,819,779,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 893,819,779,423 is 29986047.
Find LCM of 893,819,779,423 with Prime Factorization
| 3 | 893, 819, 779, 423 |
| 3 | 893, 273, 779, 141 |
| 19 | 893, 91, 779, 47 |
| 47 | 47, 91, 41, 47 |
| 1, 91, 41, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 19 x 47 x 1 x 91 x 41 x 1 = 29986047
Therefore, the lowest common multiple of 893,819,779,423 is 29986047.
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.
893 x 819 x 779 x 423 = 240997859739
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.
893 : 1, 19, 47, 893
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
779 : 1, 19, 41, 779
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 893,819,779,423, is 1.
Now, the common factors can be found like this.
893:19x 47
819:3x 3x 7x 13
779:19x 41
423:3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 19x 47 = 8037
Therefore, the value for common factors is 8037.
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 = 240997859739/(1x8037)
LCM = 240997859739/8037
LCM = 29986047
Thus, we can understand that the LCM of 893,819,779,423 is 29986047.
