Given numbers are 456,403,143

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

The LCM of 456,403,143 is 2021448.

Find LCM of 456,403,143 with Prime Factorization

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

13 x 456 x 31 x 11 = 2021448

Therefore, the lowest common multiple of 456,403,143 is 2021448.

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.

456 x 403 x 143 = 26278824

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.

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

403 : 1, 13, 31, 403

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,403,143, is 1.

Now, the common factors can be found like this.

456:2x 2x 2x 3x 19

403:13x 31

143:11x 13

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 = 26278824/(1x13)

LCM = 26278824/13

LCM = 2021448

Thus, we can understand that the LCM of 456,403,143 is 2021448.

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