Given numbers are 721,696,412,423,578
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,696,412,423,578 is 20448500184.
Find LCM of 721,696,412,423,578 with Prime Factorization
| 2 | 721, 696, 412, 423, 578 |
| 2 | 721, 348, 206, 423, 289 |
| 3 | 721, 174, 103, 423, 289 |
| 103 | 721, 58, 103, 141, 289 |
| 7, 58, 1, 141, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 103 x 7 x 58 x 1 x 141 x 289 = 20448500184
Therefore, the lowest common multiple of 721,696,412,423,578 is 20448500184.
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.
721 x 696 x 412 x 423 x 578 = 50548692454848
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.
721 : 1, 7, 103, 721
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
412 : 1, 2, 4, 103, 206, 412
423 : 1, 3, 9, 47, 141, 423
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,696,412,423,578, is 1.
Now, the common factors can be found like this.
721:7x 103
696:2x 2x 2x 3x 29
412:2x 2x 103
423:3x 3x 47
578:2x 17x 17
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 103 = 2472
Therefore, the value for common factors is 2472.
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 = 50548692454848/(1x2472)
LCM = 50548692454848/2472
LCM = 20448500184
Thus, we can understand that the LCM of 721,696,412,423,578 is 20448500184.
