Find LCM of 161,897,774,288 with Prime Factorization
| 2 | 161, 897, 774, 288 |
| 3 | 161, 897, 387, 144 |
| 3 | 161, 299, 129, 48 |
| 23 | 161, 299, 43, 16 |
| 7, 13, 43, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 23 x 7 x 13 x 43 x 16 = 25919712
Therefore, the lowest common multiple of 161,897,774,288 is 25919712.
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 897 x 774 x 288 = 32192282304
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
897 : 1, 3, 13, 23, 39, 69, 299, 897
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,897,774,288, is 1.
Now, the common factors can be found like this.
161:7x 23
897:3x 13x 23
774:2x 3x 3x 43
288:2x 2x 2x 2x 2x 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 3x 3x 3x 23 = 1242
Therefore, the value for common factors is 1242.
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 = 32192282304/(1x1242)
LCM = 32192282304/1242
LCM = 25919712
Thus, we can understand that the LCM of 161,897,774,288 is 25919712.
