Find LCM of 684,319,836,403,731 with Prime Factorization
| 2 | 684, 319, 836, 403, 731 |
| 2 | 342, 319, 418, 403, 731 |
| 11 | 171, 319, 209, 403, 731 |
| 19 | 171, 29, 19, 403, 731 |
| 9, 29, 1, 403, 731 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 9 x 29 x 1 x 403 x 731 = 64279014228
Therefore, the lowest common multiple of 684,319,836,403,731 is 64279014228.
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.
684 x 319 x 836 x 403 x 731 = 53737255894608
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
319 : 1, 11, 29, 319
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
403 : 1, 13, 31, 403
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,319,836,403,731, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
319:11x 29
836:2x 2x 11x 19
403:13x 31
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 2x 11x 19 = 836
Therefore, the value for common factors is 836.
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 = 53737255894608/(1x836)
LCM = 53737255894608/836
LCM = 64279014228
Thus, we can understand that the LCM of 684,319,836,403,731 is 64279014228.
