Given numbers are 393,279,557

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

The LCM of 393,279,557 is 20357793.

Find LCM of 393,279,557 with Prime Factorization

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

3 x 131 x 93 x 557 = 20357793

Therefore, the lowest common multiple of 393,279,557 is 20357793.

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.

393 x 279 x 557 = 61073379

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.

393 : 1, 3, 131, 393

279 : 1, 3, 9, 31, 93, 279

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,279,557, is 1.

Now, the common factors can be found like this.

393:3x 131

279:3x 3x 31

557:557

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 = 61073379/(1x3)

LCM = 61073379/3

LCM = 20357793

Thus, we can understand that the LCM of 393,279,557 is 20357793.

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

• LCM of 183, 560, 177
