Find LCM of 684,353,486,478,478 with Prime Factorization
| 2 | 684, 353, 486, 478, 478 |
| 3 | 342, 353, 243, 239, 239 |
| 3 | 114, 353, 81, 239, 239 |
| 239 | 38, 353, 27, 239, 239 |
| 38, 353, 27, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 239 x 38 x 353 x 27 x 1 x 1 = 1558089756
Therefore, the lowest common multiple of 684,353,486,478,478 is 1558089756.
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.
684 x 353 x 486 x 478 x 478 = 26811608521248
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
353 : 1, 353
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
478 : 1, 2, 239, 478
478 : 1, 2, 239, 478
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,353,486,478,478, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
353:353
486:2x 3x 3x 3x 3x 3
478:2x 239
478:2x 239
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 3x 3x 239 = 17208
Therefore, the value for common factors is 17208.
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 = 26811608521248/(1x17208)
LCM = 26811608521248/17208
LCM = 1558089756
Thus, we can understand that the LCM of 684,353,486,478,478 is 1558089756.
