Given numbers are 521,723,993

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

The LCM of 521,723,993 is 124682073.

Find LCM of 521,723,993 with Prime Factorization

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

3 x 521 x 241 x 331 = 124682073

Therefore, the lowest common multiple of 521,723,993 is 124682073.

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 723 x 993 = 374046219

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

723 : 1, 3, 241, 723

993 : 1, 3, 331, 993

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,723,993, is 1.

Now, the common factors can be found like this.

521:521

723:3x 241

993:3x 331

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 = 374046219/(1x3)

LCM = 374046219/3

LCM = 124682073

Thus, we can understand that the LCM of 521,723,993 is 124682073.

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

• LCM of 856, 370, 566
