Find LCM of 168,732,368,756,144 with Prime Factorization
| 2 | 168, 732, 368, 756, 144 |
| 2 | 84, 366, 184, 378, 72 |
| 2 | 42, 183, 92, 189, 36 |
| 2 | 21, 183, 46, 189, 18 |
| 3 | 21, 183, 23, 189, 9 |
| 3 | 7, 61, 23, 63, 3 |
| 7 | 7, 61, 23, 21, 1 |
| 1, 61, 23, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 7 x 1 x 61 x 23 x 3 x 1 = 4242672
Therefore, the lowest common multiple of 168,732,368,756,144 is 4242672.
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.
168 x 732 x 368 x 756 x 144 = 4926658609152
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,732,368,756,144, is 4.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
732:2x 2x 3x 61
368:2x 2x 2x 2x 23
756:2x 2x 3x 3x 3x 7
144:2x 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 2x 2x 2x 2x 2x 2x 2x 2x 3x 3x 3x 3x 7 = 290304
Therefore, the value for common factors is 290304.
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 = 4926658609152/(4x290304)
LCM = 4926658609152/1161216
LCM = 4242672
Thus, we can understand that the LCM of 168,732,368,756,144 is 4242672.
