Given numbers are 431,474,862,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,474,862,405 is 27579690.
Find LCM of 431,474,862,405 with Prime Factorization
| 2 | 431, 474, 862, 405 |
| 3 | 431, 237, 431, 405 |
| 431 | 431, 79, 431, 135 |
| 1, 79, 1, 135 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 431 x 1 x 79 x 1 x 135 = 27579690
Therefore, the lowest common multiple of 431,474,862,405 is 27579690.
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 474 x 862 x 405 = 71321078340
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
474 : 1, 2, 3, 6, 79, 158, 237, 474
862 : 1, 2, 431, 862
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,474,862,405, is 1.
Now, the common factors can be found like this.
431:431
474:2x 3x 79
862:2x 431
405:3x 3x 3x 3x 5
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 = 71321078340/(1x2586)
LCM = 71321078340/2586
LCM = 27579690
Thus, we can understand that the LCM of 431,474,862,405 is 27579690.
