Find LCM of 429,903,572,144,721 with Prime Factorization
| 2 | 429, 903, 572, 144, 721 |
| 2 | 429, 903, 286, 72, 721 |
| 3 | 429, 903, 143, 36, 721 |
| 7 | 143, 301, 143, 12, 721 |
| 11 | 143, 43, 143, 12, 103 |
| 13 | 13, 43, 13, 12, 103 |
| 1, 43, 1, 12, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 13 x 1 x 43 x 1 x 12 x 103 = 638413776
Therefore, the lowest common multiple of 429,903,572,144,721 is 638413776.
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.
429 x 903 x 572 x 144 x 721 = 23005878831936
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.
429 : 1, 3, 11, 13, 33, 39, 143, 429
903 : 1, 3, 7, 21, 43, 129, 301, 903
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,903,572,144,721, is 1.
Now, the common factors can be found like this.
429:3x 11x 13
903:3x 7x 43
572:2x 2x 11x 13
144:2x 2x 2x 2x 3x 3
721:7x 103
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 3x 3x 7x 11x 13 = 36036
Therefore, the value for common factors is 36036.
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 = 23005878831936/(1x36036)
LCM = 23005878831936/36036
LCM = 638413776
Thus, we can understand that the LCM of 429,903,572,144,721 is 638413776.
