Given numbers are 921,289,521,789

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

The LCM of 921,289,521,789 is 36471274887.

Find LCM of 921,289,521,789 with Prime Factorization

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

3 x 307 x 289 x 521 x 263 = 36471274887

Therefore, the lowest common multiple of 921,289,521,789 is 36471274887.

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.

921 x 289 x 521 x 789 = 109413824661

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.

921 : 1, 3, 307, 921

289 : 1, 17, 289

521 : 1, 521

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,289,521,789, is 1.

Now, the common factors can be found like this.

921:3x 307

289:17x 17

521:521

789:3x 263

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

3 = 3

Therefore, the value for common factors is 3.

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 = 109413824661/(1x3)

LCM = 109413824661/3

LCM = 36471274887

Thus, we can understand that the LCM of 921,289,521,789 is 36471274887.
