Given numbers are 345,917,842,105,738
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 345,917,842,105,738 is 32764657590.
Find LCM of 345,917,842,105,738 with Prime Factorization
| 2 | 345, 917, 842, 105, 738 |
| 3 | 345, 917, 421, 105, 369 |
| 5 | 115, 917, 421, 35, 123 |
| 7 | 23, 917, 421, 7, 123 |
| 23, 131, 421, 1, 123 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 23 x 131 x 421 x 1 x 123 = 32764657590
Therefore, the lowest common multiple of 345,917,842,105,738 is 32764657590.
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.
345 x 917 x 842 x 105 x 738 = 20641734281700
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
917 : 1, 7, 131, 917
842 : 1, 2, 421, 842
105 : 1, 3, 5, 7, 15, 21, 35, 105
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,917,842,105,738, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
917:7x 131
842:2x 421
105:3x 5x 7
738:2x 3x 3x 41
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 5x 7 = 630
Therefore, the value for common factors is 630.
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 = 20641734281700/(1x630)
LCM = 20641734281700/630
LCM = 32764657590
Thus, we can understand that the LCM of 345,917,842,105,738 is 32764657590.
