The LCM of 626,407,738,817,243 is 2073867134922.
Find LCM of 626,407,738,817,243 with Prime Factorization
| 2 | 626, 407, 738, 817, 243 |
| 3 | 313, 407, 369, 817, 243 |
| 3 | 313, 407, 123, 817, 81 |
| 313, 407, 41, 817, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 313 x 407 x 41 x 817 x 27 = 2073867134922
Therefore, the lowest common multiple of 626,407,738,817,243 is 2073867134922.
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.
626 x 407 x 738 x 817 x 243 = 37329608428596
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.
626 : 1, 2, 313, 626
407 : 1, 11, 37, 407
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
817 : 1, 19, 43, 817
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,407,738,817,243, is 1.
Now, the common factors can be found like this.
626:2x 313
407:11x 37
738:2x 3x 3x 41
817:19x 43
243:3x 3x 3x 3x 3
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 3 = 18
Therefore, the value for common factors is 18.
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 = 37329608428596/(1x18)
LCM = 37329608428596/18
LCM = 2073867134922
Thus, we can understand that the LCM of 626,407,738,817,243 is 2073867134922.
