Given numbers are 138,759,363,351
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 138,759,363,351 is 1953666.
Find LCM of 138,759,363,351 with Prime Factorization
| 3 | 138, 759, 363, 351 |
| 11 | 46, 253, 121, 117 |
| 23 | 46, 23, 11, 117 |
| 2, 1, 11, 117 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 23 x 2 x 1 x 11 x 117 = 1953666
Therefore, the lowest common multiple of 138,759,363,351 is 1953666.
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.
138 x 759 x 363 x 351 = 13345492446
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.
138 : 1, 2, 3, 6, 23, 46, 69, 138
759 : 1, 3, 11, 23, 33, 69, 253, 759
363 : 1, 3, 11, 33, 121, 363
351 : 1, 3, 9, 13, 27, 39, 117, 351
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,759,363,351, is 3.
Now, the common factors can be found like this.
138:2x 3x 23
759:3x 11x 23
363:3x 11x 11
351:3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11x 23 = 2277
Therefore, the value for common factors is 2277.
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 = 13345492446/(3x2277)
LCM = 13345492446/6831
LCM = 1953666
Thus, we can understand that the LCM of 138,759,363,351 is 1953666.
