Given numbers are 171,791,725,285,722
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 171,791,725,285,722 is 3726440550.
Find LCM of 171,791,725,285,722 with Prime Factorization
| 3 | 171, 791, 725, 285, 722 |
| 5 | 57, 791, 725, 95, 722 |
| 19 | 57, 791, 145, 19, 722 |
| 3, 791, 145, 1, 38 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 3 x 791 x 145 x 1 x 38 = 3726440550
Therefore, the lowest common multiple of 171,791,725,285,722 is 3726440550.
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.
171 x 791 x 725 x 285 x 722 = 20178675578250
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.
171 : 1, 3, 9, 19, 57, 171
791 : 1, 7, 113, 791
725 : 1, 5, 25, 29, 145, 725
285 : 1, 3, 5, 15, 19, 57, 95, 285
722 : 1, 2, 19, 38, 361, 722
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,791,725,285,722, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
791:7x 113
725:5x 5x 29
285:3x 5x 19
722:2x 19x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 19x 19 = 5415
Therefore, the value for common factors is 5415.
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 = 20178675578250/(1x5415)
LCM = 20178675578250/5415
LCM = 3726440550
Thus, we can understand that the LCM of 171,791,725,285,722 is 3726440550.
