Given numbers are 844,390,771,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,390,771,429 is 465267660.
Find LCM of 844,390,771,429 with Prime Factorization
| 2 | 844, 390, 771, 429 |
| 3 | 422, 195, 771, 429 |
| 13 | 422, 65, 257, 143 |
| 422, 5, 257, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 422 x 5 x 257 x 11 = 465267660
Therefore, the lowest common multiple of 844,390,771,429 is 465267660.
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.
844 x 390 x 771 x 429 = 108872632440
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.
844 : 1, 2, 4, 211, 422, 844
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
771 : 1, 3, 257, 771
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,390,771,429, is 1.
Now, the common factors can be found like this.
844:2x 2x 211
390:2x 3x 5x 13
771:3x 257
429:3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 13 = 234
Therefore, the value for common factors is 234.
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 = 108872632440/(1x234)
LCM = 108872632440/234
LCM = 465267660
Thus, we can understand that the LCM of 844,390,771,429 is 465267660.
