Given numbers are 975,405,489,123,651
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 975,405,489,123,651 is 38176804575.
Find LCM of 975,405,489,123,651 with Prime Factorization
| 3 | 975, 405, 489, 123, 651 |
| 5 | 325, 135, 163, 41, 217 |
| 65, 27, 163, 41, 217 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 65 x 27 x 163 x 41 x 217 = 38176804575
Therefore, the lowest common multiple of 975,405,489,123,651 is 38176804575.
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.
975 x 405 x 489 x 123 x 651 = 15461605852875
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.
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
489 : 1, 3, 163, 489
123 : 1, 3, 41, 123
651 : 1, 3, 7, 21, 31, 93, 217, 651
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,405,489,123,651, is 3.
Now, the common factors can be found like this.
975:3x 5x 5x 13
405:3x 3x 3x 3x 5
489:3x 163
123:3x 41
651:3x 7x 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 3x 3x 5 = 135
Therefore, the value for common factors is 135.
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 = 15461605852875/(3x135)
LCM = 15461605852875/405
LCM = 38176804575
Thus, we can understand that the LCM of 975,405,489,123,651 is 38176804575.
