Given numbers are 403,217,531,354

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

The LCM of 403,217,531,354 is 2995902.

Find LCM of 403,217,531,354 with Prime Factorization

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

3 x 31 x 59 x 13 x 7 x 3 x 2 = 2995902

Therefore, the lowest common multiple of 403,217,531,354 is 2995902.

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 217 x 531 x 354 = 16438514274

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

217 : 1, 7, 31, 217

531 : 1, 3, 9, 59, 177, 531

354 : 1, 2, 3, 6, 59, 118, 177, 354

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,217,531,354, is 1.

Now, the common factors can be found like this.

403:13x 31

217:7x 31

531:3x 3x 59

354:2x 3x 59

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

3x 31x 59 = 5487

Therefore, the value for common factors is 5487.

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 = 16438514274/(1x5487)

LCM = 16438514274/5487

LCM = 2995902

Thus, we can understand that the LCM of 403,217,531,354 is 2995902.
