Given numbers are 442,561,946,839
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,561,946,839 is 526219122.
Find LCM of 442,561,946,839 with Prime Factorization
| 2 | 442, 561, 946, 839 |
| 11 | 221, 561, 473, 839 |
| 17 | 221, 51, 43, 839 |
| 13, 3, 43, 839 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 13 x 3 x 43 x 839 = 526219122
Therefore, the lowest common multiple of 442,561,946,839 is 526219122.
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.
442 x 561 x 946 x 839 = 196805951628
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
561 : 1, 3, 11, 17, 33, 51, 187, 561
946 : 1, 2, 11, 22, 43, 86, 473, 946
839 : 1, 839
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,561,946,839, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
561:3x 11x 17
946:2x 11x 43
839:839
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 17 = 374
Therefore, the value for common factors is 374.
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 = 196805951628/(1x374)
LCM = 196805951628/374
LCM = 526219122
Thus, we can understand that the LCM of 442,561,946,839 is 526219122.
