Find LCM of 745,330,399,494,731 with Prime Factorization
| 2 | 745, 330, 399, 494, 731 |
| 3 | 745, 165, 399, 247, 731 |
| 5 | 745, 55, 133, 247, 731 |
| 19 | 149, 11, 133, 247, 731 |
| 149, 11, 7, 13, 731 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 149 x 11 x 7 x 13 x 731 = 62145913830
Therefore, the lowest common multiple of 745,330,399,494,731 is 62145913830.
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.
745 x 330 x 399 x 494 x 731 = 35423170883100
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.
745 : 1, 5, 149, 745
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
399 : 1, 3, 7, 19, 21, 57, 133, 399
494 : 1, 2, 13, 19, 26, 38, 247, 494
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,330,399,494,731, is 1.
Now, the common factors can be found like this.
745:5x 149
330:2x 3x 5x 11
399:3x 7x 19
494:2x 13x 19
731:17x 43
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 19 = 570
Therefore, the value for common factors is 570.
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 = 35423170883100/(1x570)
LCM = 35423170883100/570
LCM = 62145913830
Thus, we can understand that the LCM of 745,330,399,494,731 is 62145913830.
