Given numbers are 115,282,258,430
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,282,258,430 is 1394490.
Find LCM of 115,282,258,430 with Prime Factorization
| 2 | 115, 282, 258, 430 |
| 3 | 115, 141, 129, 215 |
| 5 | 115, 47, 43, 215 |
| 43 | 23, 47, 43, 43 |
| 23, 47, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 43 x 23 x 47 x 1 x 1 = 1394490
Therefore, the lowest common multiple of 115,282,258,430 is 1394490.
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.
115 x 282 x 258 x 430 = 3597784200
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.
115 : 1, 5, 23, 115
282 : 1, 2, 3, 6, 47, 94, 141, 282
258 : 1, 2, 3, 6, 43, 86, 129, 258
430 : 1, 2, 5, 10, 43, 86, 215, 430
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,282,258,430, is 1.
Now, the common factors can be found like this.
115:5x 23
282:2x 3x 47
258:2x 3x 43
430:2x 5x 43
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 3x 5x 43 = 2580
Therefore, the value for common factors is 2580.
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 = 3597784200/(1x2580)
LCM = 3597784200/2580
LCM = 1394490
Thus, we can understand that the LCM of 115,282,258,430 is 1394490.
