Find LCM of 386,731,774,399,245 with Prime Factorization
| 2 | 386, 731, 774, 399, 245 |
| 3 | 193, 731, 387, 399, 245 |
| 7 | 193, 731, 129, 133, 245 |
| 43 | 193, 731, 129, 19, 35 |
| 193, 17, 3, 19, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 43 x 193 x 17 x 3 x 19 x 35 = 11821344570
Therefore, the lowest common multiple of 386,731,774,399,245 is 11821344570.
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.
386 x 731 x 774 x 399 x 245 = 21349348293420
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.
386 : 1, 2, 193, 386
731 : 1, 17, 43, 731
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
399 : 1, 3, 7, 19, 21, 57, 133, 399
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,731,774,399,245, is 1.
Now, the common factors can be found like this.
386:2x 193
731:17x 43
774:2x 3x 3x 43
399:3x 7x 19
245:5x 7x 7
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 43 = 1806
Therefore, the value for common factors is 1806.
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 = 21349348293420/(1x1806)
LCM = 21349348293420/1806
LCM = 11821344570
Thus, we can understand that the LCM of 386,731,774,399,245 is 11821344570.
