Find LCM of 240,675,724,320 with Prime Factorization
| 2 | 240, 675, 724, 320 |
| 2 | 120, 675, 362, 160 |
| 2 | 60, 675, 181, 80 |
| 2 | 30, 675, 181, 40 |
| 3 | 15, 675, 181, 20 |
| 5 | 5, 225, 181, 20 |
| 1, 45, 181, 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 45 x 181 x 4 = 7819200
Therefore, the lowest common multiple of 240,675,724,320 is 7819200.
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 675 x 724 x 320 = 37532160000
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
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
724 : 1, 2, 4, 181, 362, 724
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,675,724,320, is 1.
Now, the common factors can be found like this.
240:2x 2x 2x 2x 3x 5
675:3x 3x 3x 5x 5
724:2x 2x 181
320:2x 2x 2x 2x 2x 2x 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 2x 2x 3x 5x 5 = 4800
Therefore, the value for common factors is 4800.
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 = 37532160000/(1x4800)
LCM = 37532160000/4800
LCM = 7819200
Thus, we can understand that the LCM of 240,675,724,320 is 7819200.
