Given numbers are 423,291,279,521

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

The LCM of 423,291,279,521 is 662691681.

Find LCM of 423,291,279,521 with Prime Factorization

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

3 x 3 x 47 x 97 x 31 x 521 = 662691681

Therefore, the lowest common multiple of 423,291,279,521 is 662691681.

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 291 x 279 x 521 = 17892675387

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

291 : 1, 3, 97, 291

279 : 1, 3, 9, 31, 93, 279

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,291,279,521, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

291:3x 97

279:3x 3x 31

521:521

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 17892675387/(1x27)

LCM = 17892675387/27

LCM = 662691681

Thus, we can understand that the LCM of 423,291,279,521 is 662691681.
