Given numbers are 463,243,457,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 463,243,457,642 is 11003155182.
Find LCM of 463,243,457,642 with Prime Factorization
| 3 | 463, 243, 457, 642 |
| 463, 81, 457, 214 |
Multiply the prime numbers at the bottom and the left side.
3 x 463 x 81 x 457 x 214 = 11003155182
Therefore, the lowest common multiple of 463,243,457,642 is 11003155182.
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.
463 x 243 x 457 x 642 = 33009465546
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.
463 : 1, 463
243 : 1, 3, 9, 27, 81, 243
457 : 1, 457
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 463,243,457,642, is 1.
Now, the common factors can be found like this.
463:463
243:3x 3x 3x 3x 3
457:457
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 33009465546/(1x3)
LCM = 33009465546/3
LCM = 11003155182
Thus, we can understand that the LCM of 463,243,457,642 is 11003155182.
