Find LCM of 340,455,208,704 with Prime Factorization
| 2 | 340, 455, 208, 704 |
| 2 | 170, 455, 104, 352 |
| 2 | 85, 455, 52, 176 |
| 2 | 85, 455, 26, 88 |
| 5 | 85, 455, 13, 44 |
| 13 | 17, 91, 13, 44 |
| 17, 7, 1, 44 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 13 x 17 x 7 x 1 x 44 = 5445440
Therefore, the lowest common multiple of 340,455,208,704 is 5445440.
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.
340 x 455 x 208 x 704 = 22653030400
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.
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
455 : 1, 5, 7, 13, 35, 65, 91, 455
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,455,208,704, is 1.
Now, the common factors can be found like this.
340:2x 2x 5x 17
455:5x 7x 13
208:2x 2x 2x 2x 13
704:2x 2x 2x 2x 2x 2x 11
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 5x 13 = 4160
Therefore, the value for common factors is 4160.
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 = 22653030400/(1x4160)
LCM = 22653030400/4160
LCM = 5445440
Thus, we can understand that the LCM of 340,455,208,704 is 5445440.
