Given numbers are 608,682,684,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 608,682,684,715 is 121286880.
Find LCM of 608,682,684,715 with Prime Factorization
| 2 | 608, 682, 684, 715 |
| 2 | 304, 341, 342, 715 |
| 11 | 152, 341, 171, 715 |
| 19 | 152, 31, 171, 65 |
| 8, 31, 9, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 8 x 31 x 9 x 65 = 121286880
Therefore, the lowest common multiple of 608,682,684,715 is 121286880.
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.
608 x 682 x 684 x 715 = 202791663360
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.
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
682 : 1, 2, 11, 22, 31, 62, 341, 682
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 608,682,684,715, is 1.
Now, the common factors can be found like this.
608:2x 2x 2x 2x 2x 19
682:2x 11x 31
684:2x 2x 3x 3x 19
715:5x 11x 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 11x 19 = 1672
Therefore, the value for common factors is 1672.
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 = 202791663360/(1x1672)
LCM = 202791663360/1672
LCM = 121286880
Thus, we can understand that the LCM of 608,682,684,715 is 121286880.
