Find LCM of 389,642,352,210,336 with Prime Factorization
| 2 | 389, 642, 352, 210, 336 |
| 2 | 389, 321, 176, 105, 168 |
| 2 | 389, 321, 88, 105, 84 |
| 2 | 389, 321, 44, 105, 42 |
| 3 | 389, 321, 22, 105, 21 |
| 7 | 389, 107, 22, 35, 7 |
| 389, 107, 22, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 389 x 107 x 22 x 5 x 1 = 1538386080
Therefore, the lowest common multiple of 389,642,352,210,336 is 1538386080.
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.
389 x 642 x 352 x 210 x 336 = 6202772674560
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.
389 : 1, 389
642 : 1, 2, 3, 6, 107, 214, 321, 642
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,642,352,210,336, is 1.
Now, the common factors can be found like this.
389:389
642:2x 3x 107
352:2x 2x 2x 2x 2x 11
210:2x 3x 5x 7
336:2x 2x 2x 2x 3x 7
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 3x 3x 7 = 4032
Therefore, the value for common factors is 4032.
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 = 6202772674560/(1x4032)
LCM = 6202772674560/4032
LCM = 1538386080
Thus, we can understand that the LCM of 389,642,352,210,336 is 1538386080.
