Given numbers are 657,381,129,678

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

The LCM of 657,381,129,678 is 810860202.

Find LCM of 657,381,129,678 with Prime Factorization

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

3 x 219 x 127 x 43 x 226 = 810860202

Therefore, the lowest common multiple of 657,381,129,678 is 810860202.

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.

657 x 381 x 129 x 678 = 21893225454

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.

657 : 1, 3, 9, 73, 219, 657

381 : 1, 3, 127, 381

129 : 1, 3, 43, 129

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

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,381,129,678, is 3.

Now, the common factors can be found like this.

657:3x 3x 73

381:3x 127

129:3x 43

678:2x 3x 113

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 21893225454/(3x9)

LCM = 21893225454/27

LCM = 810860202

Thus, we can understand that the LCM of 657,381,129,678 is 810860202.
