Given numbers are 729,153,280,773,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,153,280,773,621 is 61693841160.
Find LCM of 729,153,280,773,621 with Prime Factorization
| 3 | 729, 153, 280, 773, 621 |
| 3 | 243, 51, 280, 773, 207 |
| 3 | 81, 17, 280, 773, 69 |
| 27, 17, 280, 773, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 27 x 17 x 280 x 773 x 23 = 61693841160
Therefore, the lowest common multiple of 729,153,280,773,621 is 61693841160.
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 153 x 280 x 773 x 621 = 14991603401880
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
153 : 1, 3, 9, 17, 51, 153
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
773 : 1, 773
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,153,280,773,621, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
153:3x 3x 17
280:2x 2x 2x 5x 7
773:773
621:3x 3x 3x 23
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 3x 3x 3 = 243
Therefore, the value for common factors is 243.
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 = 14991603401880/(1x243)
LCM = 14991603401880/243
LCM = 61693841160
Thus, we can understand that the LCM of 729,153,280,773,621 is 61693841160.
