Given numbers are 423,471,521,681,493

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

The LCM of 423,471,521,681,493 is 3872135260341.

Find LCM of 423,471,521,681,493 with Prime Factorization

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

3 x 141 x 157 x 521 x 227 x 493 = 3872135260341

Therefore, the lowest common multiple of 423,471,521,681,493 is 3872135260341.

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.

423 x 471 x 521 x 681 x 493 = 34849217343069

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.

423 : 1, 3, 9, 47, 141, 423

471 : 1, 3, 157, 471

521 : 1, 521

681 : 1, 3, 227, 681

493 : 1, 17, 29, 493

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,471,521,681,493, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

471:3x 157

521:521

681:3x 227

493:17x 29

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 34849217343069/(1x9)

LCM = 34849217343069/9

LCM = 3872135260341

Thus, we can understand that the LCM of 423,471,521,681,493 is 3872135260341.
