Given numbers are 717,808,401,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,808,401,162 is 6272470872.
Find LCM of 717,808,401,162 with Prime Factorization
| 2 | 717, 808, 401, 162 |
| 3 | 717, 404, 401, 81 |
| 239, 404, 401, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 239 x 404 x 401 x 27 = 6272470872
Therefore, the lowest common multiple of 717,808,401,162 is 6272470872.
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 808 x 401 x 162 = 37634825232
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
808 : 1, 2, 4, 8, 101, 202, 404, 808
401 : 1, 401
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,808,401,162, is 1.
Now, the common factors can be found like this.
717:3x 239
808:2x 2x 2x 101
401:401
162:2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 37634825232/(1x6)
LCM = 37634825232/6
LCM = 6272470872
Thus, we can understand that the LCM of 717,808,401,162 is 6272470872.
