Given numbers are 183,720,160,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 183,720,160,646 is 28372320.
Find LCM of 183,720,160,646 with Prime Factorization
| 2 | 183, 720, 160, 646 |
| 2 | 183, 360, 80, 323 |
| 2 | 183, 180, 40, 323 |
| 2 | 183, 90, 20, 323 |
| 3 | 183, 45, 10, 323 |
| 5 | 61, 15, 10, 323 |
| 61, 3, 2, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 61 x 3 x 2 x 323 = 28372320
Therefore, the lowest common multiple of 183,720,160,646 is 28372320.
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.
183 x 720 x 160 x 646 = 13618713600
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.
183 : 1, 3, 61, 183
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 183,720,160,646, is 1.
Now, the common factors can be found like this.
183:3x 61
720:2x 2x 2x 2x 3x 3x 5
160:2x 2x 2x 2x 2x 5
646:2x 17x 19
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 3x 5 = 480
Therefore, the value for common factors is 480.
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 = 13618713600/(1x480)
LCM = 13618713600/480
LCM = 28372320
Thus, we can understand that the LCM of 183,720,160,646 is 28372320.
