Given numbers are 465,408,897,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 465,408,897,661 is 12498690360.
Find LCM of 465,408,897,661 with Prime Factorization
| 3 | 465, 408, 897, 661 |
| 155, 136, 299, 661 |
Multiply the prime numbers at the bottom and the left side.
3 x 155 x 136 x 299 x 661 = 12498690360
Therefore, the lowest common multiple of 465,408,897,661 is 12498690360.
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.
465 x 408 x 897 x 661 = 112488213240
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.
465 : 1, 3, 5, 15, 31, 93, 155, 465
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
897 : 1, 3, 13, 23, 39, 69, 299, 897
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 465,408,897,661, is 1.
Now, the common factors can be found like this.
465:3x 5x 31
408:2x 2x 2x 3x 17
897:3x 13x 23
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 112488213240/(1x9)
LCM = 112488213240/9
LCM = 12498690360
Thus, we can understand that the LCM of 465,408,897,661 is 12498690360.
