The LCM of 693,494,205,363,138 is 17755567830.
Find LCM of 693,494,205,363,138 with Prime Factorization
| 2 | 693, 494, 205, 363, 138 |
| 3 | 693, 247, 205, 363, 69 |
| 11 | 231, 247, 205, 121, 23 |
| 21, 247, 205, 11, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 21 x 247 x 205 x 11 x 23 = 17755567830
Therefore, the lowest common multiple of 693,494,205,363,138 is 17755567830.
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.
693 x 494 x 205 x 363 x 138 = 3515602430340
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
494 : 1, 2, 13, 19, 26, 38, 247, 494
205 : 1, 5, 41, 205
363 : 1, 3, 11, 33, 121, 363
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,494,205,363,138, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
494:2x 13x 19
205:5x 41
363:3x 11x 11
138:2x 3x 23
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 11 = 198
Therefore, the value for common factors is 198.
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 = 3515602430340/(1x198)
LCM = 3515602430340/198
LCM = 17755567830
Thus, we can understand that the LCM of 693,494,205,363,138 is 17755567830.
