Given numbers are 717,441,289,398
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,441,289,398 is 12123203778.
Find LCM of 717,441,289,398 with Prime Factorization
| 3 | 717, 441, 289, 398 |
| 239, 147, 289, 398 |
Multiply the prime numbers at the bottom and the left side.
3 x 239 x 147 x 289 x 398 = 12123203778
Therefore, the lowest common multiple of 717,441,289,398 is 12123203778.
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 441 x 289 x 398 = 36369611334
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
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
289 : 1, 17, 289
398 : 1, 2, 199, 398
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,441,289,398, is 1.
Now, the common factors can be found like this.
717:3x 239
441:3x 3x 7x 7
289:17x 17
398:2x 199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 36369611334/(1x3)
LCM = 36369611334/3
LCM = 12123203778
Thus, we can understand that the LCM of 717,441,289,398 is 12123203778.
