Given numbers are 431,289,559,860
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,289,559,860 is 1392569620.
Find LCM of 431,289,559,860 with Prime Factorization
| 43 | 431, 289, 559, 860 |
| 431, 289, 13, 20 |
Multiply the prime numbers at the bottom and the left side.
43 x 431 x 289 x 13 x 20 = 1392569620
Therefore, the lowest common multiple of 431,289,559,860 is 1392569620.
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 289 x 559 x 860 = 59880493660
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
289 : 1, 17, 289
559 : 1, 13, 43, 559
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,289,559,860, is 1.
Now, the common factors can be found like this.
431:431
289:17x 17
559:13x 43
860:2x 2x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
43 = 43
Therefore, the value for common factors is 43.
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 = 59880493660/(1x43)
LCM = 59880493660/43
LCM = 1392569620
Thus, we can understand that the LCM of 431,289,559,860 is 1392569620.
