Given numbers are 891,492,369,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 891,492,369,129 is 6283332.
Find LCM of 891,492,369,129 with Prime Factorization
| 3 | 891, 492, 369, 129 |
| 3 | 297, 164, 123, 43 |
| 41 | 99, 164, 41, 43 |
| 99, 4, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 41 x 99 x 4 x 1 x 43 = 6283332
Therefore, the lowest common multiple of 891,492,369,129 is 6283332.
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.
891 x 492 x 369 x 129 = 20866945572
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
369 : 1, 3, 9, 41, 123, 369
129 : 1, 3, 43, 129
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,492,369,129, is 3.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
492:2x 2x 3x 41
369:3x 3x 41
129:3x 43
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 41 = 1107
Therefore, the value for common factors is 1107.
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 = 20866945572/(3x1107)
LCM = 20866945572/3321
LCM = 6283332
Thus, we can understand that the LCM of 891,492,369,129 is 6283332.
