The LCM of 738,228,309,873,781 is 218826518724.
Find LCM of 738,228,309,873,781 with Prime Factorization
| 2 | 738, 228, 309, 873, 781 |
| 3 | 369, 114, 309, 873, 781 |
| 3 | 123, 38, 103, 291, 781 |
| 41, 38, 103, 97, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 41 x 38 x 103 x 97 x 781 = 218826518724
Therefore, the lowest common multiple of 738,228,309,873,781 is 218826518724.
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.
738 x 228 x 309 x 873 x 781 = 35449896033288
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.
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
309 : 1, 3, 103, 309
873 : 1, 3, 9, 97, 291, 873
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,228,309,873,781, is 1.
Now, the common factors can be found like this.
738:2x 3x 3x 41
228:2x 2x 3x 19
309:3x 103
873:3x 3x 97
781:11x 71
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 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 35449896033288/(1x162)
LCM = 35449896033288/162
LCM = 218826518724
Thus, we can understand that the LCM of 738,228,309,873,781 is 218826518724.
