Given numbers are 338,209,621,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,209,621,138 is 43868682.
Find LCM of 338,209,621,138 with Prime Factorization
| 2 | 338, 209, 621, 138 |
| 3 | 169, 209, 621, 69 |
| 23 | 169, 209, 207, 23 |
| 169, 209, 9, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 169 x 209 x 9 x 1 = 43868682
Therefore, the lowest common multiple of 338,209,621,138 is 43868682.
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 209 x 621 x 138 = 6053878116
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
209 : 1, 11, 19, 209
621 : 1, 3, 9, 23, 27, 69, 207, 621
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 338,209,621,138, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
209:11x 19
621:3x 3x 3x 23
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 23 = 138
Therefore, the value for common factors is 138.
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 = 6053878116/(1x138)
LCM = 6053878116/138
LCM = 43868682
Thus, we can understand that the LCM of 338,209,621,138 is 43868682.
