Given numbers are 455,616,717,811,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,616,717,811,556 is 3236300787720.
Find LCM of 455,616,717,811,556 with Prime Factorization
| 2 | 455, 616, 717, 811, 556 |
| 2 | 455, 308, 717, 811, 278 |
| 7 | 455, 154, 717, 811, 139 |
| 65, 22, 717, 811, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 65 x 22 x 717 x 811 x 139 = 3236300787720
Therefore, the lowest common multiple of 455,616,717,811,556 is 3236300787720.
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.
455 x 616 x 717 x 811 x 556 = 90616422056160
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
717 : 1, 3, 239, 717
811 : 1, 811
556 : 1, 2, 4, 139, 278, 556
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,616,717,811,556, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
616:2x 2x 2x 7x 11
717:3x 239
811:811
556:2x 2x 139
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 7 = 28
Therefore, the value for common factors is 28.
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 = 90616422056160/(1x28)
LCM = 90616422056160/28
LCM = 3236300787720
Thus, we can understand that the LCM of 455,616,717,811,556 is 3236300787720.
