Given numbers are 717,987,717,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,987,717,779 is 183760647.
Find LCM of 717,987,717,779 with Prime Factorization
| 3 | 717, 987, 717, 779 |
| 239 | 239, 329, 239, 779 |
| 1, 329, 1, 779 |
Multiply the prime numbers at the bottom and the left side.
3 x 239 x 1 x 329 x 1 x 779 = 183760647
Therefore, the lowest common multiple of 717,987,717,779 is 183760647.
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 987 x 717 x 779 = 395269151697
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
987 : 1, 3, 7, 21, 47, 141, 329, 987
717 : 1, 3, 239, 717
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,987,717,779, is 1.
Now, the common factors can be found like this.
717:3x 239
987:3x 7x 47
717:3x 239
779:19x 41
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 239 = 2151
Therefore, the value for common factors is 2151.
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 = 395269151697/(1x2151)
LCM = 395269151697/2151
LCM = 183760647
Thus, we can understand that the LCM of 717,987,717,779 is 183760647.
