Given numbers are 521,989,391

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

The LCM of 521,989,391 is 8759573.

Find LCM of 521,989,391 with Prime Factorization

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

23 x 521 x 43 x 17 = 8759573

Therefore, the lowest common multiple of 521,989,391 is 8759573.

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 989 x 391 = 201470179

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

989 : 1, 23, 43, 989

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,989,391, is 1.

Now, the common factors can be found like this.

521:521

989:23x 43

391:17x 23

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

23 = 23

Therefore, the value for common factors is 23.

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 = 201470179/(1x23)

LCM = 201470179/23

LCM = 8759573

Thus, we can understand that the LCM of 521,989,391 is 8759573.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 451, 342, 702
• LCM of 707, 172, 170
