Given numbers are 929,819,649,905,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 929,819,649,905,405 is 4021938275355.
Find LCM of 929,819,649,905,405 with Prime Factorization
| 3 | 929, 819, 649, 905, 405 |
| 3 | 929, 273, 649, 905, 135 |
| 5 | 929, 91, 649, 905, 45 |
| 929, 91, 649, 181, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 929 x 91 x 649 x 181 x 9 = 4021938275355
Therefore, the lowest common multiple of 929,819,649,905,405 is 4021938275355.
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.
929 x 819 x 649 x 905 x 405 = 180987222390975
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.
929 : 1, 929
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
649 : 1, 11, 59, 649
905 : 1, 5, 181, 905
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 929,819,649,905,405, is 1.
Now, the common factors can be found like this.
929:929
819:3x 3x 7x 13
649:11x 59
905:5x 181
405:3x 3x 3x 3x 5
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 5 = 45
Therefore, the value for common factors is 45.
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 = 180987222390975/(1x45)
LCM = 180987222390975/45
LCM = 4021938275355
Thus, we can understand that the LCM of 929,819,649,905,405 is 4021938275355.
