The LCM of 338,731,684,504,778 is 460190681496.
Find LCM of 338,731,684,504,778 with Prime Factorization
| 2 | 338, 731, 684, 504, 778 |
| 2 | 169, 731, 342, 252, 389 |
| 3 | 169, 731, 171, 126, 389 |
| 3 | 169, 731, 57, 42, 389 |
| 169, 731, 19, 14, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 169 x 731 x 19 x 14 x 389 = 460190681496
Therefore, the lowest common multiple of 338,731,684,504,778 is 460190681496.
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.
338 x 731 x 684 x 504 x 778 = 66267458135424
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.
338 : 1, 2, 13, 26, 169, 338
731 : 1, 17, 43, 731
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,731,684,504,778, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
731:17x 43
684:2x 2x 3x 3x 19
504:2x 2x 2x 3x 3x 7
778:2x 389
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 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 66267458135424/(1x144)
LCM = 66267458135424/144
LCM = 460190681496
Thus, we can understand that the LCM of 338,731,684,504,778 is 460190681496.
