Given numbers are 251,891,385,663,330
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,891,385,663,330 is 3459726270.
Find LCM of 251,891,385,663,330 with Prime Factorization
| 3 | 251, 891, 385, 663, 330 |
| 5 | 251, 297, 385, 221, 110 |
| 11 | 251, 297, 77, 221, 22 |
| 251, 27, 7, 221, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 251 x 27 x 7 x 221 x 2 = 3459726270
Therefore, the lowest common multiple of 251,891,385,663,330 is 3459726270.
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.
251 x 891 x 385 x 663 x 330 = 18838209540150
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.
251 : 1, 251
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
385 : 1, 5, 7, 11, 35, 55, 77, 385
663 : 1, 3, 13, 17, 39, 51, 221, 663
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,891,385,663,330, is 1.
Now, the common factors can be found like this.
251:251
891:3x 3x 3x 3x 11
385:5x 7x 11
663:3x 13x 17
330:2x 3x 5x 11
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 5x 11x 11 = 5445
Therefore, the value for common factors is 5445.
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 = 18838209540150/(1x5445)
LCM = 18838209540150/5445
LCM = 3459726270
Thus, we can understand that the LCM of 251,891,385,663,330 is 3459726270.
