Given numbers are 403,143,442,581

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

The LCM of 403,143,442,581 is 87569482.

Find LCM of 403,143,442,581 with Prime Factorization

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

13 x 31 x 11 x 34 x 581 = 87569482

Therefore, the lowest common multiple of 403,143,442,581 is 87569482.

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.

403 x 143 x 442 x 581 = 14799242458

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.

403 : 1, 13, 31, 403

143 : 1, 11, 13, 143

442 : 1, 2, 13, 17, 26, 34, 221, 442

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,143,442,581, is 1.

Now, the common factors can be found like this.

403:13x 31

143:11x 13

442:2x 13x 17

581:7x 83

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 14799242458/(1x169)

LCM = 14799242458/169

LCM = 87569482

Thus, we can understand that the LCM of 403,143,442,581 is 87569482.
