Given numbers are 729,103,662,546,783
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,103,662,546,783 is 131178340566.
Find LCM of 729,103,662,546,783 with Prime Factorization
| 2 | 729, 103, 662, 546, 783 |
| 3 | 729, 103, 331, 273, 783 |
| 3 | 243, 103, 331, 91, 261 |
| 3 | 81, 103, 331, 91, 87 |
| 27, 103, 331, 91, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 27 x 103 x 331 x 91 x 29 = 131178340566
Therefore, the lowest common multiple of 729,103,662,546,783 is 131178340566.
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 103 x 662 x 546 x 783 = 21250891171692
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
103 : 1, 103
662 : 1, 2, 331, 662
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,103,662,546,783, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
103:103
662:2x 331
546:2x 3x 7x 13
783:3x 3x 3x 29
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 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 21250891171692/(1x162)
LCM = 21250891171692/162
LCM = 131178340566
Thus, we can understand that the LCM of 729,103,662,546,783 is 131178340566.
