Find LCM of 338,432,576,191 with Prime Factorization
| 2 | 338, 432, 576, 191 |
| 2 | 169, 216, 288, 191 |
| 2 | 169, 108, 144, 191 |
| 2 | 169, 54, 72, 191 |
| 3 | 169, 27, 36, 191 |
| 3 | 169, 9, 12, 191 |
| 169, 3, 4, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 169 x 3 x 4 x 191 = 55778112
Therefore, the lowest common multiple of 338,432,576,191 is 55778112.
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.
338 x 432 x 576 x 191 = 16064096256
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.
338 : 1, 2, 13, 26, 169, 338
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
191 : 1, 191
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,432,576,191, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
432:2x 2x 2x 2x 3x 3x 3
576:2x 2x 2x 2x 2x 2x 3x 3
191:191
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 2x 2x 3x 3 = 288
Therefore, the value for common factors is 288.
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 = 16064096256/(1x288)
LCM = 16064096256/288
LCM = 55778112
Thus, we can understand that the LCM of 338,432,576,191 is 55778112.
