Given numbers are 381,143,235,403

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

The LCM of 381,143,235,403 is 396908655.

Find LCM of 381,143,235,403 with Prime Factorization

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

13 x 381 x 11 x 235 x 31 = 396908655

Therefore, the lowest common multiple of 381,143,235,403 is 396908655.

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.

381 x 143 x 235 x 403 = 5159812515

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.

381 : 1, 3, 127, 381

143 : 1, 11, 13, 143

235 : 1, 5, 47, 235

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,143,235,403, is 1.

Now, the common factors can be found like this.

381:3x 127

143:11x 13

235:5x 47

403:13x 31

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

13 = 13

Therefore, the value for common factors is 13.

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 = 5159812515/(1x13)

LCM = 5159812515/13

LCM = 396908655

Thus, we can understand that the LCM of 381,143,235,403 is 396908655.

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