Given numbers are 129,423,890,836,272
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 129,423,890,836,272 is 460133681040.
Find LCM of 129,423,890,836,272 with Prime Factorization
| 2 | 129, 423, 890, 836, 272 |
| 2 | 129, 423, 445, 418, 136 |
| 3 | 129, 423, 445, 209, 68 |
| 43, 141, 445, 209, 68 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 141 x 445 x 209 x 68 = 460133681040
Therefore, the lowest common multiple of 129,423,890,836,272 is 460133681040.
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.
129 x 423 x 890 x 836 x 272 = 11043208344960
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.
129 : 1, 3, 43, 129
423 : 1, 3, 9, 47, 141, 423
890 : 1, 2, 5, 10, 89, 178, 445, 890
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,423,890,836,272, is 1.
Now, the common factors can be found like this.
129:3x 43
423:3x 3x 47
890:2x 5x 89
836:2x 2x 11x 19
272:2x 2x 2x 2x 17
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 11043208344960/(1x24)
LCM = 11043208344960/24
LCM = 460133681040
Thus, we can understand that the LCM of 129,423,890,836,272 is 460133681040.
