Given numbers are 138,574,326,871,507
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 138,574,326,871,507 is 73098774294.
Find LCM of 138,574,326,871,507 with Prime Factorization
| 2 | 138, 574, 326, 871, 507 |
| 3 | 69, 287, 163, 871, 507 |
| 13 | 23, 287, 163, 871, 169 |
| 23, 287, 163, 67, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 23 x 287 x 163 x 67 x 13 = 73098774294
Therefore, the lowest common multiple of 138,574,326,871,507 is 73098774294.
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 574 x 326 x 871 x 507 = 11403408789864
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
574 : 1, 2, 7, 14, 41, 82, 287, 574
326 : 1, 2, 163, 326
871 : 1, 13, 67, 871
507 : 1, 3, 13, 39, 169, 507
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,574,326,871,507, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
574:2x 7x 41
326:2x 163
871:13x 67
507:3x 13x 13
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 11403408789864/(1x156)
LCM = 11403408789864/156
LCM = 73098774294
Thus, we can understand that the LCM of 138,574,326,871,507 is 73098774294.
