Given numbers are 621,797,423,893,939
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,797,423,893,939 is 138339345933.
Find LCM of 621,797,423,893,939 with Prime Factorization
| 3 | 621, 797, 423, 893, 939 |
| 3 | 207, 797, 141, 893, 313 |
| 47 | 69, 797, 47, 893, 313 |
| 69, 797, 1, 19, 313 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 47 x 69 x 797 x 1 x 19 x 313 = 138339345933
Therefore, the lowest common multiple of 621,797,423,893,939 is 138339345933.
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.
621 x 797 x 423 x 893 x 939 = 175552629988977
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
797 : 1, 797
423 : 1, 3, 9, 47, 141, 423
893 : 1, 19, 47, 893
939 : 1, 3, 313, 939
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,797,423,893,939, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
797:797
423:3x 3x 47
893:19x 47
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.
3x 3x 3x 47 = 1269
Therefore, the value for common factors is 1269.
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 = 175552629988977/(1x1269)
LCM = 175552629988977/1269
LCM = 138339345933
Thus, we can understand that the LCM of 621,797,423,893,939 is 138339345933.
