Given numbers are 717,121,486,69
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,121,486,69 is 323256582.
Find LCM of 717,121,486,69 with Prime Factorization
| 3 | 717, 121, 486, 69 |
| 239, 121, 162, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 239 x 121 x 162 x 23 = 323256582
Therefore, the lowest common multiple of 717,121,486,69 is 323256582.
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.
717 x 121 x 486 x 69 = 2909309238
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.
717 : 1, 3, 239, 717
121 : 1, 11, 121
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
69 : 1, 3, 23, 69
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,121,486,69, is 1.
Now, the common factors can be found like this.
717:3x 239
121:11x 11
486:2x 3x 3x 3x 3x 3
69:3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 2909309238/(1x9)
LCM = 2909309238/9
LCM = 323256582
Thus, we can understand that the LCM of 717,121,486,69 is 323256582.
