Given numbers are 729,745,495,540
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,745,495,540 is 23896620.
Find LCM of 729,745,495,540 with Prime Factorization
| 3 | 729, 745, 495, 540 |
| 3 | 243, 745, 165, 180 |
| 3 | 81, 745, 55, 60 |
| 5 | 27, 745, 55, 20 |
| 27, 149, 11, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 27 x 149 x 11 x 4 = 23896620
Therefore, the lowest common multiple of 729,745,495,540 is 23896620.
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 745 x 495 x 540 = 145171966500
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
745 : 1, 5, 149, 745
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,745,495,540, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
745:5x 149
495:3x 3x 5x 11
540:2x 2x 3x 3x 3x 5
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 3x 5x 5 = 6075
Therefore, the value for common factors is 6075.
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 = 145171966500/(1x6075)
LCM = 145171966500/6075
LCM = 23896620
Thus, we can understand that the LCM of 729,745,495,540 is 23896620.
