Find LCM of 389,772,228,642,193 with Prime Factorization
| 2 | 389, 772, 228, 642, 193 |
| 2 | 389, 386, 114, 321, 193 |
| 3 | 389, 193, 57, 321, 193 |
| 193 | 389, 193, 19, 107, 193 |
| 389, 1, 19, 107, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 193 x 389 x 1 x 19 x 107 x 1 = 1831578492
Therefore, the lowest common multiple of 389,772,228,642,193 is 1831578492.
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 772 x 228 x 642 x 193 = 8483871574944
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
772 : 1, 2, 4, 193, 386, 772
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
642 : 1, 2, 3, 6, 107, 214, 321, 642
193 : 1, 193
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,772,228,642,193, is 1.
Now, the common factors can be found like this.
389:389
772:2x 2x 193
228:2x 2x 3x 19
642:2x 3x 107
193:193
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 193 = 4632
Therefore, the value for common factors is 4632.
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 = 8483871574944/(1x4632)
LCM = 8483871574944/4632
LCM = 1831578492
Thus, we can understand that the LCM of 389,772,228,642,193 is 1831578492.
