Given numbers are 451,589,860,361,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 451,589,860,361,686 is 1488805652180.
Find LCM of 451,589,860,361,686 with Prime Factorization
| 2 | 451, 589, 860, 361, 686 |
| 19 | 451, 589, 430, 361, 343 |
| 451, 31, 430, 19, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 451 x 31 x 430 x 19 x 343 = 1488805652180
Therefore, the lowest common multiple of 451,589,860,361,686 is 1488805652180.
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.
451 x 589 x 860 x 361 x 686 = 56574614782840
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.
451 : 1, 11, 41, 451
589 : 1, 19, 31, 589
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
361 : 1, 19, 361
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,589,860,361,686, is 1.
Now, the common factors can be found like this.
451:11x 41
589:19x 31
860:2x 2x 5x 43
361:19x 19
686:2x 7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19 = 38
Therefore, the value for common factors is 38.
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 = 56574614782840/(1x38)
LCM = 56574614782840/38
LCM = 1488805652180
Thus, we can understand that the LCM of 451,589,860,361,686 is 1488805652180.
