Given numbers are 591,862,431,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 591,862,431,138 is 11717166.
Find LCM of 591,862,431,138 with Prime Factorization
| 2 | 591, 862, 431, 138 |
| 3 | 591, 431, 431, 69 |
| 431 | 197, 431, 431, 23 |
| 197, 1, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 431 x 197 x 1 x 1 x 23 = 11717166
Therefore, the lowest common multiple of 591,862,431,138 is 11717166.
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.
591 x 862 x 431 x 138 = 30300591276
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.
591 : 1, 3, 197, 591
862 : 1, 2, 431, 862
431 : 1, 431
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 591,862,431,138, is 1.
Now, the common factors can be found like this.
591:3x 197
862:2x 431
431:431
138:2x 3x 23
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 431 = 2586
Therefore, the value for common factors is 2586.
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 = 30300591276/(1x2586)
LCM = 30300591276/2586
LCM = 11717166
Thus, we can understand that the LCM of 591,862,431,138 is 11717166.
