Given numbers are 217,403,521,433

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

The LCM of 217,403,521,433 is 636397853.

Find LCM of 217,403,521,433 with Prime Factorization

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

31 x 7 x 13 x 521 x 433 = 636397853

Therefore, the lowest common multiple of 217,403,521,433 is 636397853.

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.

217 x 403 x 521 x 433 = 19728333443

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.

217 : 1, 7, 31, 217

403 : 1, 13, 31, 403

521 : 1, 521

433 : 1, 433

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,403,521,433, is 1.

Now, the common factors can be found like this.

217:7x 31

403:13x 31

521:521

433:433

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

31 = 31

Therefore, the value for common factors is 31.

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 = 19728333443/(1x31)

LCM = 19728333443/31

LCM = 636397853

Thus, we can understand that the LCM of 217,403,521,433 is 636397853.
