Given numbers are 712,408,912,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 712,408,912,388 is 133846032.
Find LCM of 712,408,912,388 with Prime Factorization
| 2 | 712, 408, 912, 388 |
| 2 | 356, 204, 456, 194 |
| 2 | 178, 102, 228, 97 |
| 3 | 89, 51, 114, 97 |
| 89, 17, 38, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 89 x 17 x 38 x 97 = 133846032
Therefore, the lowest common multiple of 712,408,912,388 is 133846032.
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.
712 x 408 x 912 x 388 = 102793752576
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.
712 : 1, 2, 4, 8, 89, 178, 356, 712
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
388 : 1, 2, 4, 97, 194, 388
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 712,408,912,388, is 4.
Now, the common factors can be found like this.
712:2x 2x 2x 89
408:2x 2x 2x 3x 17
912:2x 2x 2x 2x 3x 19
388:2x 2x 97
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 2x 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 102793752576/(4x192)
LCM = 102793752576/768
LCM = 133846032
Thus, we can understand that the LCM of 712,408,912,388 is 133846032.
