The LCM of 163,242,605,345,817 is 11118446790.
Find LCM of 163,242,605,345,817 with Prime Factorization
| 5 | 163, 242, 605, 345, 817 |
| 11 | 163, 242, 121, 69, 817 |
| 11 | 163, 22, 11, 69, 817 |
| 163, 2, 1, 69, 817 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 11 x 163 x 2 x 1 x 69 x 817 = 11118446790
Therefore, the lowest common multiple of 163,242,605,345,817 is 11118446790.
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.
163 x 242 x 605 x 345 x 817 = 6726660307950
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.
163 : 1, 163
242 : 1, 2, 11, 22, 121, 242
605 : 1, 5, 11, 55, 121, 605
345 : 1, 3, 5, 15, 23, 69, 115, 345
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,242,605,345,817, is 1.
Now, the common factors can be found like this.
163:163
242:2x 11x 11
605:5x 11x 11
345:3x 5x 23
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 11 = 605
Therefore, the value for common factors is 605.
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 = 6726660307950/(1x605)
LCM = 6726660307950/605
LCM = 11118446790
Thus, we can understand that the LCM of 163,242,605,345,817 is 11118446790.
