Find LCM of 289,456,376,684 with Prime Factorization
| 2 | 289, 456, 376, 684 |
| 2 | 289, 228, 188, 342 |
| 2 | 289, 114, 94, 171 |
| 3 | 289, 57, 47, 171 |
| 19 | 289, 19, 47, 57 |
| 289, 1, 47, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 289 x 1 x 47 x 3 = 18581544
Therefore, the lowest common multiple of 289,456,376,684 is 18581544.
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.
289 x 456 x 376 x 684 = 33892736256
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.
289 : 1, 17, 289
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
376 : 1, 2, 4, 8, 47, 94, 188, 376
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,456,376,684, is 1.
Now, the common factors can be found like this.
289:17x 17
456:2x 2x 2x 3x 19
376:2x 2x 2x 47
684:2x 2x 3x 3x 19
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 19 = 1824
Therefore, the value for common factors is 1824.
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 = 33892736256/(1x1824)
LCM = 33892736256/1824
LCM = 18581544
Thus, we can understand that the LCM of 289,456,376,684 is 18581544.
