Given numbers are 261,551,465,443,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,551,465,443,403 is 4426626555.
Find LCM of 261,551,465,443,403 with Prime Factorization
| 3 | 261, 551, 465, 443, 403 |
| 29 | 87, 551, 155, 443, 403 |
| 31 | 3, 19, 155, 443, 403 |
| 3, 19, 5, 443, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 29 x 31 x 3 x 19 x 5 x 443 x 13 = 4426626555
Therefore, the lowest common multiple of 261,551,465,443,403 is 4426626555.
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.
261 x 551 x 465 x 443 x 403 = 11938611818835
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.
261 : 1, 3, 9, 29, 87, 261
551 : 1, 19, 29, 551
465 : 1, 3, 5, 15, 31, 93, 155, 465
443 : 1, 443
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,551,465,443,403, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
551:19x 29
465:3x 5x 31
443:443
403:13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 29x 31 = 2697
Therefore, the value for common factors is 2697.
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 = 11938611818835/(1x2697)
LCM = 11938611818835/2697
LCM = 4426626555
Thus, we can understand that the LCM of 261,551,465,443,403 is 4426626555.
