Given numbers are 729,445,356,786,401
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,445,356,786,401 is 68165276220.
Find LCM of 729,445,356,786,401 with Prime Factorization
| 2 | 729, 445, 356, 786, 401 |
| 3 | 729, 445, 178, 393, 401 |
| 89 | 243, 445, 178, 131, 401 |
| 243, 5, 2, 131, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 89 x 243 x 5 x 2 x 131 x 401 = 68165276220
Therefore, the lowest common multiple of 729,445,356,786,401 is 68165276220.
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.
729 x 445 x 356 x 786 x 401 = 36400257501480
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.
729 : 1, 3, 9, 27, 81, 243, 729
445 : 1, 5, 89, 445
356 : 1, 2, 4, 89, 178, 356
786 : 1, 2, 3, 6, 131, 262, 393, 786
401 : 1, 401
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,445,356,786,401, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
445:5x 89
356:2x 2x 89
786:2x 3x 131
401:401
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 89 = 534
Therefore, the value for common factors is 534.
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 = 36400257501480/(1x534)
LCM = 36400257501480/534
LCM = 68165276220
Thus, we can understand that the LCM of 729,445,356,786,401 is 68165276220.
