Given numbers are 1,388,557,692
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1,388,557,692 is 37388068.
Find LCM of 1,388,557,692 with Prime Factorization
| 2 | 1, 388, 557, 692 |
| 2 | 1, 194, 557, 346 |
| 1, 97, 557, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 1 x 97 x 557 x 173 = 37388068
Therefore, the lowest common multiple of 1,388,557,692 is 37388068.
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.
1 x 388 x 557 x 692 = 149552272
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.
1 : 1
388 : 1, 2, 4, 97, 194, 388
557 : 1, 557
692 : 1, 2, 4, 173, 346, 692
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,388,557,692, is 1.
Now, the common factors can be found like this.
1:
388:2x 2x 97
557:557
692:2x 2x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 149552272/(1x4)
LCM = 149552272/4
LCM = 37388068
Thus, we can understand that the LCM of 1,388,557,692 is 37388068.
