Given numbers are 405,782,902,736,898
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,782,902,736,898 is 1026135332640.
Find LCM of 405,782,902,736,898 with Prime Factorization
| 2 | 405, 782, 902, 736, 898 |
| 23 | 405, 391, 451, 368, 449 |
| 405, 17, 451, 16, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 405 x 17 x 451 x 16 x 449 = 1026135332640
Therefore, the lowest common multiple of 405,782,902,736,898 is 1026135332640.
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 782 x 902 x 736 x 898 = 188808901205760
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
782 : 1, 2, 17, 23, 34, 46, 391, 782
902 : 1, 2, 11, 22, 41, 82, 451, 902
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
898 : 1, 2, 449, 898
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,782,902,736,898, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
782:2x 17x 23
902:2x 11x 41
736:2x 2x 2x 2x 2x 23
898:2x 449
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 23 = 184
Therefore, the value for common factors is 184.
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 = 188808901205760/(1x184)
LCM = 188808901205760/184
LCM = 1026135332640
Thus, we can understand that the LCM of 405,782,902,736,898 is 1026135332640.
