Given numbers are 401,678,457,693

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 401,678,457,693 is 28701344826.

Find LCM of 401,678,457,693 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 401 x 226 x 457 x 231 = 28701344826

Therefore, the lowest common multiple of 401,678,457,693 is 28701344826.

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.

401 x 678 x 457 x 693 = 86104034478

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.

401 : 1, 401

678 : 1, 2, 3, 6, 113, 226, 339, 678

457 : 1, 457

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,678,457,693, is 1.

Now, the common factors can be found like this.

401:401

678:2x 3x 113

457:457

693:3x 3x 7x 11

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 = 86104034478/(1x3)

LCM = 86104034478/3

LCM = 28701344826

Thus, we can understand that the LCM of 401,678,457,693 is 28701344826.
