Given numbers are 521,345,669

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

The LCM of 521,345,669 is 40083135.

Find LCM of 521,345,669 with Prime Factorization

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

3 x 521 x 115 x 223 = 40083135

Therefore, the lowest common multiple of 521,345,669 is 40083135.

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 345 x 669 = 120249405

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

345 : 1, 3, 5, 15, 23, 69, 115, 345

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,345,669, is 1.

Now, the common factors can be found like this.

521:521

345:3x 5x 23

669:3x 223

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 = 120249405/(1x3)

LCM = 120249405/3

LCM = 40083135

Thus, we can understand that the LCM of 521,345,669 is 40083135.

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

• LCM of 452, 624, 405
• LCM of 619, 681, 206
