Given numbers are 389,807,618

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

The LCM of 389,807,618 is 64668138.

Find LCM of 389,807,618 with Prime Factorization

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

3 x 389 x 269 x 206 = 64668138

Therefore, the lowest common multiple of 389,807,618 is 64668138.

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.

389 x 807 x 618 = 194004414

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.

389 : 1, 389

807 : 1, 3, 269, 807

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,807,618, is 1.

Now, the common factors can be found like this.

389:389

807:3x 269

618:2x 3x 103

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 = 194004414/(1x3)

LCM = 194004414/3

LCM = 64668138

Thus, we can understand that the LCM of 389,807,618 is 64668138.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 385, 114, 956
• LCM of 160, 275, 343
