Given numbers are 289,427,391,939
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 289,427,391,939 is 2665134591.
Find LCM of 289,427,391,939 with Prime Factorization
17 | 289, 427, 391, 939 |
17, 427, 23, 939 |
Multiply the prime numbers at the bottom and the left side.
17 x 17 x 427 x 23 x 939 = 2665134591
Therefore, the lowest common multiple of 289,427,391,939 is 2665134591.
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.
289 x 427 x 391 x 939 = 45307288047
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.
289 : 1, 17, 289
427 : 1, 7, 61, 427
391 : 1, 17, 23, 391
939 : 1, 3, 313, 939
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,427,391,939, is 1.
Now, the common factors can be found like this.
289:17x 17
427:7x 61
391:17x 23
939:3x 313
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 = 45307288047/(1x17)
LCM = 45307288047/17
LCM = 2665134591
Thus, we can understand that the LCM of 289,427,391,939 is 2665134591.
