Given numbers are 293,644,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 293,644,391 is 3207764.
Find LCM of 293,644,391 with Prime Factorization
| 23 | 293, 644, 391 |
| 293, 28, 17 |
Multiply the prime numbers at the bottom and the left side.
23 x 293 x 28 x 17 = 3207764
Therefore, the lowest common multiple of 293,644,391 is 3207764.
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.
293 x 644 x 391 = 73778572
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.
293 : 1, 293
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 293,644,391, is 1.
Now, the common factors can be found like this.
293:293
644:2x 2x 7x 23
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.
23 = 23
Therefore, the value for common factors is 23.
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 = 73778572/(1x23)
LCM = 73778572/23
LCM = 3207764
Thus, we can understand that the LCM of 293,644,391 is 3207764.
