Find LCM of 203,798,815,162,655 with Prime Factorization
| 2 | 203, 798, 815, 162, 655 |
| 3 | 203, 399, 815, 81, 655 |
| 5 | 203, 133, 815, 27, 655 |
| 7 | 203, 133, 163, 27, 131 |
| 29, 19, 163, 27, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 29 x 19 x 163 x 27 x 131 = 66710402010
Therefore, the lowest common multiple of 203,798,815,162,655 is 66710402010.
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.
203 x 798 x 815 x 162 x 655 = 14009184422100
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.
203 : 1, 7, 29, 203
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
815 : 1, 5, 163, 815
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,798,815,162,655, is 1.
Now, the common factors can be found like this.
203:7x 29
798:2x 3x 7x 19
815:5x 163
162:2x 3x 3x 3x 3
655:5x 131
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 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 14009184422100/(1x210)
LCM = 14009184422100/210
LCM = 66710402010
Thus, we can understand that the LCM of 203,798,815,162,655 is 66710402010.
