Given numbers are 391,805,598
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,805,598 is 355810.
Find LCM of 391,805,598 with Prime Factorization
| 23 | 391, 805, 598 |
| 17, 35, 26 |
Multiply the prime numbers at the bottom and the left side.
23 x 17 x 35 x 26 = 355810
Therefore, the lowest common multiple of 391,805,598 is 355810.
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.
391 x 805 x 598 = 188223490
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.
391 : 1, 17, 23, 391
805 : 1, 5, 7, 23, 35, 115, 161, 805
598 : 1, 2, 13, 23, 26, 46, 299, 598
23 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,805,598, is 23.
Now, the common factors can be found like this.
391:17x 23
805:5x 7x 23
598:2x 13x 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 = 188223490/(23x23)
LCM = 188223490/529
LCM = 355810
Thus, we can understand that the LCM of 391,805,598 is 355810.
