Find LCM of 128,429,286,836,175 with Prime Factorization
| 2 | 128, 429, 286, 836, 175 |
| 2 | 64, 429, 143, 418, 175 |
| 11 | 32, 429, 143, 209, 175 |
| 13 | 32, 39, 13, 19, 175 |
| 32, 3, 1, 19, 175 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 13 x 32 x 3 x 1 x 19 x 175 = 182582400
Therefore, the lowest common multiple of 128,429,286,836,175 is 182582400.
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.
128 x 429 x 286 x 836 x 175 = 2297616921600
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
429 : 1, 3, 11, 13, 33, 39, 143, 429
286 : 1, 2, 11, 13, 22, 26, 143, 286
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
175 : 1, 5, 7, 25, 35, 175
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,429,286,836,175, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
429:3x 11x 13
286:2x 11x 13
836:2x 2x 11x 19
175:5x 5x 7
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 11x 11x 13 = 12584
Therefore, the value for common factors is 12584.
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 = 2297616921600/(1x12584)
LCM = 2297616921600/12584
LCM = 182582400
Thus, we can understand that the LCM of 128,429,286,836,175 is 182582400.
