Find LCM of 723,648,432,509 with Prime Factorization
| 2 | 723, 648, 432, 509 |
| 2 | 723, 324, 216, 509 |
| 2 | 723, 162, 108, 509 |
| 3 | 723, 81, 54, 509 |
| 3 | 241, 27, 18, 509 |
| 3 | 241, 9, 6, 509 |
| 241, 3, 2, 509 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 241 x 3 x 2 x 509 = 158979024
Therefore, the lowest common multiple of 723,648,432,509 is 158979024.
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.
723 x 648 x 432 x 509 = 103018407552
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.
723 : 1, 3, 241, 723
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
509 : 1, 509
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,648,432,509, is 1.
Now, the common factors can be found like this.
723:3x 241
648:2x 2x 2x 3x 3x 3x 3
432:2x 2x 2x 2x 3x 3x 3
509:509
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 3x 3x 3x 3 = 648
Therefore, the value for common factors is 648.
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 = 103018407552/(1x648)
LCM = 103018407552/648
LCM = 158979024
Thus, we can understand that the LCM of 723,648,432,509 is 158979024.
