Given numbers are 462,162,861,422
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 462,162,861,422 is 107912574.
Find LCM of 462,162,861,422 with Prime Factorization
| 2 | 462, 162, 861, 422 |
| 3 | 231, 81, 861, 211 |
| 7 | 77, 27, 287, 211 |
| 11, 27, 41, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 27 x 41 x 211 = 107912574
Therefore, the lowest common multiple of 462,162,861,422 is 107912574.
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.
462 x 162 x 861 x 422 = 27193968648
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
861 : 1, 3, 7, 21, 41, 123, 287, 861
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,162,861,422, is 1.
Now, the common factors can be found like this.
462:2x 3x 7x 11
162:2x 3x 3x 3x 3
861:3x 7x 41
422:2x 211
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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 27193968648/(1x252)
LCM = 27193968648/252
LCM = 107912574
Thus, we can understand that the LCM of 462,162,861,422 is 107912574.
