Given numbers are 826,455,118,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 826,455,118,162 is 4348890.
Find LCM of 826,455,118,162 with Prime Factorization
| 2 | 826, 455, 118, 162 |
| 7 | 413, 455, 59, 81 |
| 59 | 59, 65, 59, 81 |
| 1, 65, 1, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 59 x 1 x 65 x 1 x 81 = 4348890
Therefore, the lowest common multiple of 826,455,118,162 is 4348890.
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.
826 x 455 x 118 x 162 = 7184366280
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.
826 : 1, 2, 7, 14, 59, 118, 413, 826
455 : 1, 5, 7, 13, 35, 65, 91, 455
118 : 1, 2, 59, 118
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 826,455,118,162, is 1.
Now, the common factors can be found like this.
826:2x 7x 59
455:5x 7x 13
118:2x 59
162:2x 3x 3x 3x 3
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 7x 59 = 1652
Therefore, the value for common factors is 1652.
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 = 7184366280/(1x1652)
LCM = 7184366280/1652
LCM = 4348890
Thus, we can understand that the LCM of 826,455,118,162 is 4348890.
