Given numbers are 221,742,229,728,523
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,742,229,728,523 is 78558528776.
Find LCM of 221,742,229,728,523 with Prime Factorization
| 2 | 221, 742, 229, 728, 523 |
| 7 | 221, 371, 229, 364, 523 |
| 13 | 221, 53, 229, 52, 523 |
| 17, 53, 229, 4, 523 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 17 x 53 x 229 x 4 x 523 = 78558528776
Therefore, the lowest common multiple of 221,742,229,728,523 is 78558528776.
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.
221 x 742 x 229 x 728 x 523 = 14297652237232
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.
221 : 1, 13, 17, 221
742 : 1, 2, 7, 14, 53, 106, 371, 742
229 : 1, 229
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
523 : 1, 523
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,742,229,728,523, is 1.
Now, the common factors can be found like this.
221:13x 17
742:2x 7x 53
229:229
728:2x 2x 2x 7x 13
523:523
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 13 = 182
Therefore, the value for common factors is 182.
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 = 14297652237232/(1x182)
LCM = 14297652237232/182
LCM = 78558528776
Thus, we can understand that the LCM of 221,742,229,728,523 is 78558528776.
