Find LCM of 161,896,305,368 with Prime Factorization
| 2 | 161, 896, 305, 368 |
| 2 | 161, 448, 305, 184 |
| 2 | 161, 224, 305, 92 |
| 2 | 161, 112, 305, 46 |
| 7 | 161, 56, 305, 23 |
| 23 | 23, 8, 305, 23 |
| 1, 8, 305, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 23 x 1 x 8 x 305 x 1 = 6285440
Therefore, the lowest common multiple of 161,896,305,368 is 6285440.
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.
161 x 896 x 305 x 368 = 16191293440
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.
161 : 1, 7, 23, 161
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
305 : 1, 5, 61, 305
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,896,305,368, is 1.
Now, the common factors can be found like this.
161:7x 23
896:2x 2x 2x 2x 2x 2x 2x 7
305:5x 61
368:2x 2x 2x 2x 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 7x 23 = 2576
Therefore, the value for common factors is 2576.
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 = 16191293440/(1x2576)
LCM = 16191293440/2576
LCM = 6285440
Thus, we can understand that the LCM of 161,896,305,368 is 6285440.
