Given numbers are 391,505,905,598
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,505,905,598 is 929223230.
Find LCM of 391,505,905,598 with Prime Factorization
| 5 | 391, 505, 905, 598 |
| 23 | 391, 101, 181, 598 |
| 17, 101, 181, 26 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 17 x 101 x 181 x 26 = 929223230
Therefore, the lowest common multiple of 391,505,905,598 is 929223230.
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 505 x 905 x 598 = 106860671450
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
505 : 1, 5, 101, 505
905 : 1, 5, 181, 905
598 : 1, 2, 13, 23, 26, 46, 299, 598
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,505,905,598, is 1.
Now, the common factors can be found like this.
391:17x 23
505:5x 101
905:5x 181
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.
5x 23 = 115
Therefore, the value for common factors is 115.
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 = 106860671450/(1x115)
LCM = 106860671450/115
LCM = 929223230
Thus, we can understand that the LCM of 391,505,905,598 is 929223230.
