Given numbers are 689,408,587,799
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,408,587,799 is 7755598968.
Find LCM of 689,408,587,799 with Prime Factorization
| 17 | 689, 408, 587, 799 |
| 689, 24, 587, 47 |
Multiply the prime numbers at the bottom and the left side.
17 x 689 x 24 x 587 x 47 = 7755598968
Therefore, the lowest common multiple of 689,408,587,799 is 7755598968.
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.
689 x 408 x 587 x 799 = 131845182456
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.
689 : 1, 13, 53, 689
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
587 : 1, 587
799 : 1, 17, 47, 799
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,408,587,799, is 1.
Now, the common factors can be found like this.
689:13x 53
408:2x 2x 2x 3x 17
587:587
799:17x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 131845182456/(1x17)
LCM = 131845182456/17
LCM = 7755598968
Thus, we can understand that the LCM of 689,408,587,799 is 7755598968.
