Given numbers are 431,961,930,886
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,961,930,886 is 5504598390.
Find LCM of 431,961,930,886 with Prime Factorization
| 2 | 431, 961, 930, 886 |
| 31 | 431, 961, 465, 443 |
| 431, 31, 15, 443 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 431 x 31 x 15 x 443 = 5504598390
Therefore, the lowest common multiple of 431,961,930,886 is 5504598390.
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.
431 x 961 x 930 x 886 = 341285100180
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.
431 : 1, 431
961 : 1, 31, 961
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
886 : 1, 2, 443, 886
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,961,930,886, is 1.
Now, the common factors can be found like this.
431:431
961:31x 31
930:2x 3x 5x 31
886:2x 443
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 31 = 62
Therefore, the value for common factors is 62.
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 = 341285100180/(1x62)
LCM = 341285100180/62
LCM = 5504598390
Thus, we can understand that the LCM of 431,961,930,886 is 5504598390.
