Find LCM of 240,407,545,960 with Prime Factorization
| 2 | 240, 407, 545, 960 |
| 2 | 120, 407, 545, 480 |
| 2 | 60, 407, 545, 240 |
| 2 | 30, 407, 545, 120 |
| 3 | 15, 407, 545, 60 |
| 5 | 5, 407, 545, 20 |
| 1, 407, 109, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 1 x 407 x 109 x 4 = 42588480
Therefore, the lowest common multiple of 240,407,545,960 is 42588480.
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.
240 x 407 x 545 x 960 = 51106176000
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.
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
407 : 1, 11, 37, 407
545 : 1, 5, 109, 545
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,407,545,960, is 1.
Now, the common factors can be found like this.
240:2x 2x 2x 2x 3x 5
407:11x 37
545:5x 109
960:2x 2x 2x 2x 2x 2x 3x 5
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 3x 5x 5 = 1200
Therefore, the value for common factors is 1200.
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 = 51106176000/(1x1200)
LCM = 51106176000/1200
LCM = 42588480
Thus, we can understand that the LCM of 240,407,545,960 is 42588480.
