Given numbers are 405,846,909,978,451
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,846,909,978,451 is 282662630910.
Find LCM of 405,846,909,978,451 with Prime Factorization
| 2 | 405, 846, 909, 978, 451 |
| 3 | 405, 423, 909, 489, 451 |
| 3 | 135, 141, 303, 163, 451 |
| 45, 47, 101, 163, 451 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 45 x 47 x 101 x 163 x 451 = 282662630910
Therefore, the lowest common multiple of 405,846,909,978,451 is 282662630910.
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.
405 x 846 x 909 x 978 x 451 = 137374038622260
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
909 : 1, 3, 9, 101, 303, 909
978 : 1, 2, 3, 6, 163, 326, 489, 978
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,846,909,978,451, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
846:2x 3x 3x 47
909:3x 3x 101
978:2x 3x 163
451:11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3 = 486
Therefore, the value for common factors is 486.
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 = 137374038622260/(1x486)
LCM = 137374038622260/486
LCM = 282662630910
Thus, we can understand that the LCM of 405,846,909,978,451 is 282662630910.
