Given numbers are 521,284,430,354

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

The LCM of 521,284,430,354 is 5630770020.

Find LCM of 521,284,430,354 with Prime Factorization

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

2 x 521 x 142 x 215 x 177 = 5630770020

Therefore, the lowest common multiple of 521,284,430,354 is 5630770020.

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.

521 x 284 x 430 x 354 = 22523080080

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.

521 : 1, 521

284 : 1, 2, 4, 71, 142, 284

430 : 1, 2, 5, 10, 43, 86, 215, 430

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 521,284,430,354, is 1.

Now, the common factors can be found like this.

521:521

284:2x 2x 71

430:2x 5x 43

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 22523080080/(1x4)

LCM = 22523080080/4

LCM = 5630770020

Thus, we can understand that the LCM of 521,284,430,354 is 5630770020.
