Given numbers are 481,221,857,814
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 481,221,857,814 is 154169158.
Find LCM of 481,221,857,814 with Prime Factorization
| 13 | 481, 221, 857, 814 |
| 37 | 37, 17, 857, 814 |
| 1, 17, 857, 22 |
Multiply the prime numbers at the bottom and the left side.
13 x 37 x 1 x 17 x 857 x 22 = 154169158
Therefore, the lowest common multiple of 481,221,857,814 is 154169158.
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.
481 x 221 x 857 x 814 = 74155364998
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.
481 : 1, 13, 37, 481
221 : 1, 13, 17, 221
857 : 1, 857
814 : 1, 2, 11, 22, 37, 74, 407, 814
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,221,857,814, is 1.
Now, the common factors can be found like this.
481:13x 37
221:13x 17
857:857
814:2x 11x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 37 = 481
Therefore, the value for common factors is 481.
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 = 74155364998/(1x481)
LCM = 74155364998/481
LCM = 154169158
Thus, we can understand that the LCM of 481,221,857,814 is 154169158.
