Find LCM of 423,720,535,396,726 with Prime Factorization
| 2 | 423, 720, 535, 396, 726 |
| 2 | 423, 360, 535, 198, 363 |
| 3 | 423, 180, 535, 99, 363 |
| 3 | 141, 60, 535, 33, 121 |
| 5 | 47, 20, 535, 11, 121 |
| 11 | 47, 4, 107, 11, 121 |
| 47, 4, 107, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 11 x 47 x 4 x 107 x 1 x 11 = 438126480
Therefore, the lowest common multiple of 423,720,535,396,726 is 438126480.
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.
423 x 720 x 535 x 396 x 726 = 46844483241600
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.
423 : 1, 3, 9, 47, 141, 423
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
535 : 1, 5, 107, 535
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,720,535,396,726, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
720:2x 2x 2x 2x 3x 3x 5
535:5x 107
396:2x 2x 3x 3x 11
726:2x 3x 11x 11
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 3x 3x 5x 11 = 106920
Therefore, the value for common factors is 106920.
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 = 46844483241600/(1x106920)
LCM = 46844483241600/106920
LCM = 438126480
Thus, we can understand that the LCM of 423,720,535,396,726 is 438126480.
