Find LCM of 394,896,210,432 with Prime Factorization
| 2 | 394, 896, 210, 432 |
| 2 | 197, 448, 105, 216 |
| 2 | 197, 224, 105, 108 |
| 2 | 197, 112, 105, 54 |
| 3 | 197, 56, 105, 27 |
| 7 | 197, 56, 35, 9 |
| 197, 8, 5, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 197 x 8 x 5 x 9 = 23829120
Therefore, the lowest common multiple of 394,896,210,432 is 23829120.
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.
394 x 896 x 210 x 432 = 32026337280
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.
394 : 1, 2, 197, 394
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,896,210,432, is 2.
Now, the common factors can be found like this.
394:2x 197
896:2x 2x 2x 2x 2x 2x 2x 7
210:2x 3x 5x 7
432:2x 2x 2x 2x 3x 3x 3
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 7 = 672
Therefore, the value for common factors is 672.
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 = 32026337280/(2x672)
LCM = 32026337280/1344
LCM = 23829120
Thus, we can understand that the LCM of 394,896,210,432 is 23829120.
