Find LCM of 896,224,353,391 with Prime Factorization
| 2 | 896, 224, 353, 391 |
| 2 | 448, 112, 353, 391 |
| 2 | 224, 56, 353, 391 |
| 2 | 112, 28, 353, 391 |
| 2 | 56, 14, 353, 391 |
| 7 | 28, 7, 353, 391 |
| 4, 1, 353, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 7 x 4 x 1 x 353 x 391 = 123668608
Therefore, the lowest common multiple of 896,224,353,391 is 123668608.
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.
896 x 224 x 353 x 391 = 27701768192
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.
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
353 : 1, 353
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 896,224,353,391, is 1.
Now, the common factors can be found like this.
896:2x 2x 2x 2x 2x 2x 2x 7
224:2x 2x 2x 2x 2x 7
353:353
391:17x 23
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 7 = 224
Therefore, the value for common factors is 224.
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 = 27701768192/(1x224)
LCM = 27701768192/224
LCM = 123668608
Thus, we can understand that the LCM of 896,224,353,391 is 123668608.
