Given numbers are 130,391,422,391,888
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 130,391,422,391,888 is 4761957720.
Find LCM of 130,391,422,391,888 with Prime Factorization
| 2 | 130, 391, 422, 391, 888 |
| 17 | 65, 391, 211, 391, 444 |
| 23 | 65, 23, 211, 23, 444 |
| 65, 1, 211, 1, 444 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 65 x 1 x 211 x 1 x 444 = 4761957720
Therefore, the lowest common multiple of 130,391,422,391,888 is 4761957720.
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.
130 x 391 x 422 x 391 x 888 = 7447701874080
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.
130 : 1, 2, 5, 10, 13, 26, 65, 130
391 : 1, 17, 23, 391
422 : 1, 2, 211, 422
391 : 1, 17, 23, 391
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,391,422,391,888, is 1.
Now, the common factors can be found like this.
130:2x 5x 13
391:17x 23
422:2x 211
391:17x 23
888:2x 2x 2x 3x 37
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 17x 23 = 1564
Therefore, the value for common factors is 1564.
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 = 7447701874080/(1x1564)
LCM = 7447701874080/1564
LCM = 4761957720
Thus, we can understand that the LCM of 130,391,422,391,888 is 4761957720.
