Given numbers are 423,509,205,943,369
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,509,205,943,369 is 1015172505.
Find LCM of 423,509,205,943,369 with Prime Factorization
| 3 | 423, 509, 205, 943, 369 |
| 3 | 141, 509, 205, 943, 123 |
| 41 | 47, 509, 205, 943, 41 |
| 47, 509, 5, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 41 x 47 x 509 x 5 x 23 x 1 = 1015172505
Therefore, the lowest common multiple of 423,509,205,943,369 is 1015172505.
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.
423 x 509 x 205 x 943 x 369 = 15358544828145
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.
423 : 1, 3, 9, 47, 141, 423
509 : 1, 509
205 : 1, 5, 41, 205
943 : 1, 23, 41, 943
369 : 1, 3, 9, 41, 123, 369
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,509,205,943,369, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
509:509
205:5x 41
943:23x 41
369:3x 3x 41
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 41x 41 = 15129
Therefore, the value for common factors is 15129.
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 = 15358544828145/(1x15129)
LCM = 15358544828145/15129
LCM = 1015172505
Thus, we can understand that the LCM of 423,509,205,943,369 is 1015172505.
