Find LCM of 321,308,734,560,864 with Prime Factorization
| 2 | 321, 308, 734, 560, 864 |
| 2 | 321, 154, 367, 280, 432 |
| 2 | 321, 77, 367, 140, 216 |
| 2 | 321, 77, 367, 70, 108 |
| 3 | 321, 77, 367, 35, 54 |
| 7 | 107, 77, 367, 35, 18 |
| 107, 11, 367, 5, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 107 x 11 x 367 x 5 x 18 = 13062440160
Therefore, the lowest common multiple of 321,308,734,560,864 is 13062440160.
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.
321 x 308 x 734 x 560 x 864 = 35111839150080
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.
321 : 1, 3, 107, 321
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
734 : 1, 2, 367, 734
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,308,734,560,864, is 1.
Now, the common factors can be found like this.
321:3x 107
308:2x 2x 7x 11
734:2x 367
560:2x 2x 2x 2x 5x 7
864:2x 2x 2x 2x 2x 3x 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 3x 7 = 2688
Therefore, the value for common factors is 2688.
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 = 35111839150080/(1x2688)
LCM = 35111839150080/2688
LCM = 13062440160
Thus, we can understand that the LCM of 321,308,734,560,864 is 13062440160.
