Given numbers are 171,573,408,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 171,573,408,162 is 39977064.
Find LCM of 171,573,408,162 with Prime Factorization
| 2 | 171, 573, 408, 162 |
| 3 | 171, 573, 204, 81 |
| 3 | 57, 191, 68, 27 |
| 19, 191, 68, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 191 x 68 x 9 = 39977064
Therefore, the lowest common multiple of 171,573,408,162 is 39977064.
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 573 x 408 x 162 = 6476284368
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
573 : 1, 3, 191, 573
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,573,408,162, is 3.
Now, the common factors can be found like this.
171:3x 3x 19
573:3x 191
408:2x 2x 2x 3x 17
162:2x 3x 3x 3x 3
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 3 = 54
Therefore, the value for common factors is 54.
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 = 6476284368/(3x54)
LCM = 6476284368/162
LCM = 39977064
Thus, we can understand that the LCM of 171,573,408,162 is 39977064.
