Given numbers are 687,960,549,715,683
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,960,549,715,683 is 3929294191680.
Find LCM of 687,960,549,715,683 with Prime Factorization
| 3 | 687, 960, 549, 715, 683 |
| 5 | 229, 320, 183, 715, 683 |
| 229, 64, 183, 143, 683 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 229 x 64 x 183 x 143 x 683 = 3929294191680
Therefore, the lowest common multiple of 687,960,549,715,683 is 3929294191680.
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.
687 x 960 x 549 x 715 x 683 = 176818238625600
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.
687 : 1, 3, 229, 687
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
549 : 1, 3, 9, 61, 183, 549
715 : 1, 5, 11, 13, 55, 65, 143, 715
683 : 1, 683
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,960,549,715,683, is 1.
Now, the common factors can be found like this.
687:3x 229
960:2x 2x 2x 2x 2x 2x 3x 5
549:3x 3x 61
715:5x 11x 13
683:683
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
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 = 176818238625600/(1x45)
LCM = 176818238625600/45
LCM = 3929294191680
Thus, we can understand that the LCM of 687,960,549,715,683 is 3929294191680.
