Given numbers are 164,605,520,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 164,605,520,728 is 18058040.
Find LCM of 164,605,520,728 with Prime Factorization
| 2 | 164, 605, 520, 728 |
| 2 | 82, 605, 260, 364 |
| 2 | 41, 605, 130, 182 |
| 5 | 41, 605, 65, 91 |
| 13 | 41, 121, 13, 91 |
| 41, 121, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 13 x 41 x 121 x 1 x 7 = 18058040
Therefore, the lowest common multiple of 164,605,520,728 is 18058040.
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.
164 x 605 x 520 x 728 = 37560723200
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.
164 : 1, 2, 4, 41, 82, 164
605 : 1, 5, 11, 55, 121, 605
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 164,605,520,728, is 1.
Now, the common factors can be found like this.
164:2x 2x 41
605:5x 11x 11
520:2x 2x 2x 5x 13
728:2x 2x 2x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 5x 13 = 2080
Therefore, the value for common factors is 2080.
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 = 37560723200/(1x2080)
LCM = 37560723200/2080
LCM = 18058040
Thus, we can understand that the LCM of 164,605,520,728 is 18058040.
