Given numbers are 481,572,860,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 481,572,860,390 is 13650780.
Find LCM of 481,572,860,390 with Prime Factorization
| 2 | 481, 572, 860, 390 |
| 2 | 481, 286, 430, 195 |
| 5 | 481, 143, 215, 195 |
| 13 | 481, 143, 43, 39 |
| 37, 11, 43, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 37 x 11 x 43 x 3 = 13650780
Therefore, the lowest common multiple of 481,572,860,390 is 13650780.
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.
481 x 572 x 860 x 390 = 92279272800
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.
481 : 1, 13, 37, 481
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,572,860,390, is 1.
Now, the common factors can be found like this.
481:13x 37
572:2x 2x 11x 13
860:2x 2x 5x 43
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 13x 13 = 6760
Therefore, the value for common factors is 6760.
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 = 92279272800/(1x6760)
LCM = 92279272800/6760
LCM = 13650780
Thus, we can understand that the LCM of 481,572,860,390 is 13650780.
