Given numbers are 231,121,551,587,171
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 231,121,551,587,171 is 2465560251.
Find LCM of 231,121,551,587,171 with Prime Factorization
| 3 | 231, 121, 551, 587, 171 |
| 11 | 77, 121, 551, 587, 57 |
| 19 | 7, 11, 551, 587, 57 |
| 7, 11, 29, 587, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 19 x 7 x 11 x 29 x 587 x 3 = 2465560251
Therefore, the lowest common multiple of 231,121,551,587,171 is 2465560251.
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.
231 x 121 x 551 x 587 x 171 = 1545906277377
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
121 : 1, 11, 121
551 : 1, 19, 29, 551
587 : 1, 587
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,121,551,587,171, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
121:11x 11
551:19x 29
587:587
171:3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 19 = 627
Therefore, the value for common factors is 627.
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 = 1545906277377/(1x627)
LCM = 1545906277377/627
LCM = 2465560251
Thus, we can understand that the LCM of 231,121,551,587,171 is 2465560251.
