Find LCM of 406,480,686,192 with Prime Factorization
| 2 | 406, 480, 686, 192 |
| 2 | 203, 240, 343, 96 |
| 2 | 203, 120, 343, 48 |
| 2 | 203, 60, 343, 24 |
| 2 | 203, 30, 343, 12 |
| 3 | 203, 15, 343, 6 |
| 7 | 203, 5, 343, 2 |
| 29, 5, 49, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 7 x 29 x 5 x 49 x 2 = 9549120
Therefore, the lowest common multiple of 406,480,686,192 is 9549120.
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.
406 x 480 x 686 x 192 = 25668034560
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.
406 : 1, 2, 7, 14, 29, 58, 203, 406
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
686 : 1, 2, 7, 14, 49, 98, 343, 686
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,480,686,192, is 2.
Now, the common factors can be found like this.
406:2x 7x 29
480:2x 2x 2x 2x 2x 3x 5
686:2x 7x 7x 7
192:2x 2x 2x 2x 2x 2x 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 2x 2x 2x 2x 2x 3x 7 = 1344
Therefore, the value for common factors is 1344.
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 = 25668034560/(2x1344)
LCM = 25668034560/2688
LCM = 9549120
Thus, we can understand that the LCM of 406,480,686,192 is 9549120.
