Given numbers are 291,783,493,221,519
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 291,783,493,221,519 is 2903834583.
Find LCM of 291,783,493,221,519 with Prime Factorization
| 3 | 291, 783, 493, 221, 519 |
| 17 | 97, 261, 493, 221, 173 |
| 29 | 97, 261, 29, 13, 173 |
| 97, 9, 1, 13, 173 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 29 x 97 x 9 x 1 x 13 x 173 = 2903834583
Therefore, the lowest common multiple of 291,783,493,221,519 is 2903834583.
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.
291 x 783 x 493 x 221 x 519 = 12884314044771
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.
291 : 1, 3, 97, 291
783 : 1, 3, 9, 27, 29, 87, 261, 783
493 : 1, 17, 29, 493
221 : 1, 13, 17, 221
519 : 1, 3, 173, 519
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,783,493,221,519, is 1.
Now, the common factors can be found like this.
291:3x 97
783:3x 3x 3x 29
493:17x 29
221:13x 17
519:3x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 17x 29 = 4437
Therefore, the value for common factors is 4437.
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 = 12884314044771/(1x4437)
LCM = 12884314044771/4437
LCM = 2903834583
Thus, we can understand that the LCM of 291,783,493,221,519 is 2903834583.
