Given numbers are 617,618,129,789

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

The LCM of 617,618,129,789 is 4312189554.

Find LCM of 617,618,129,789 with Prime Factorization

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

3 x 617 x 206 x 43 x 263 = 4312189554

Therefore, the lowest common multiple of 617,618,129,789 is 4312189554.

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.

617 x 618 x 129 x 789 = 38809705986

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.

617 : 1, 617

618 : 1, 2, 3, 6, 103, 206, 309, 618

129 : 1, 3, 43, 129

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,618,129,789, is 1.

Now, the common factors can be found like this.

617:617

618:2x 3x 103

129:3x 43

789:3x 263

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 = 38809705986/(1x9)

LCM = 38809705986/9

LCM = 4312189554

Thus, we can understand that the LCM of 617,618,129,789 is 4312189554.
