Given numbers are 862,374,143,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 862,374,143,442 is 2095522.
Find LCM of 862,374,143,442 with Prime Factorization
| 2 | 862, 374, 143, 442 |
| 11 | 431, 187, 143, 221 |
| 13 | 431, 17, 13, 221 |
| 17 | 431, 17, 1, 17 |
| 431, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 17 x 431 x 1 x 1 x 1 = 2095522
Therefore, the lowest common multiple of 862,374,143,442 is 2095522.
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.
862 x 374 x 143 x 442 = 20376855928
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.
862 : 1, 2, 431, 862
374 : 1, 2, 11, 17, 22, 34, 187, 374
143 : 1, 11, 13, 143
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,374,143,442, is 1.
Now, the common factors can be found like this.
862:2x 431
374:2x 11x 17
143:11x 13
442:2x 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 2x 11x 13x 17 = 9724
Therefore, the value for common factors is 9724.
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 = 20376855928/(1x9724)
LCM = 20376855928/9724
LCM = 2095522
Thus, we can understand that the LCM of 862,374,143,442 is 2095522.
