Find LCM of 388,147,462,451,755 with Prime Factorization
| 2 | 388, 147, 462, 451, 755 |
| 3 | 194, 147, 231, 451, 755 |
| 7 | 194, 49, 77, 451, 755 |
| 11 | 194, 7, 11, 451, 755 |
| 194, 7, 1, 41, 755 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 194 x 7 x 1 x 41 x 755 = 19421043180
Therefore, the lowest common multiple of 388,147,462,451,755 is 19421043180.
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.
388 x 147 x 462 x 451 x 755 = 8972521949160
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.
388 : 1, 2, 4, 97, 194, 388
147 : 1, 3, 7, 21, 49, 147
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
451 : 1, 11, 41, 451
755 : 1, 5, 151, 755
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,147,462,451,755, is 1.
Now, the common factors can be found like this.
388:2x 2x 97
147:3x 7x 7
462:2x 3x 7x 11
451:11x 41
755:5x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 11 = 462
Therefore, the value for common factors is 462.
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 = 8972521949160/(1x462)
LCM = 8972521949160/462
LCM = 19421043180
Thus, we can understand that the LCM of 388,147,462,451,755 is 19421043180.
