Find LCM of 401,561,374,678,718 with Prime Factorization
| 2 | 401, 561, 374, 678, 718 |
| 3 | 401, 561, 187, 339, 359 |
| 11 | 401, 187, 187, 113, 359 |
| 17 | 401, 17, 17, 113, 359 |
| 401, 1, 1, 113, 359 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 401 x 1 x 1 x 113 x 359 = 18251985774
Therefore, the lowest common multiple of 401,561,374,678,718 is 18251985774.
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.
401 x 561 x 374 x 678 x 718 = 40957456076856
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.
401 : 1, 401
561 : 1, 3, 11, 17, 33, 51, 187, 561
374 : 1, 2, 11, 17, 22, 34, 187, 374
678 : 1, 2, 3, 6, 113, 226, 339, 678
718 : 1, 2, 359, 718
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,561,374,678,718, is 1.
Now, the common factors can be found like this.
401:401
561:3x 11x 17
374:2x 11x 17
678:2x 3x 113
718:2x 359
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 11x 17 = 2244
Therefore, the value for common factors is 2244.
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 = 40957456076856/(1x2244)
LCM = 40957456076856/2244
LCM = 18251985774
Thus, we can understand that the LCM of 401,561,374,678,718 is 18251985774.
