Given numbers are 915,323,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 915,323,391 is 6797535.
Find LCM of 915,323,391 with Prime Factorization
17 | 915, 323, 391 |
915, 19, 23 |
Multiply the prime numbers at the bottom and the left side.
17 x 915 x 19 x 23 = 6797535
Therefore, the lowest common multiple of 915,323,391 is 6797535.
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.
915 x 323 x 391 = 115558095
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.
915 : 1, 3, 5, 15, 61, 183, 305, 915
323 : 1, 17, 19, 323
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,323,391, is 1.
Now, the common factors can be found like this.
915:3x 5x 61
323:17x 19
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 115558095/(1x17)
LCM = 115558095/17
LCM = 6797535
Thus, we can understand that the LCM of 915,323,391 is 6797535.
