Given numbers are 521,213,639

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

The LCM of 521,213,639 is 332919.

Find LCM of 521,213,639 with Prime Factorization

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

3 x 71 x 521 x 1 x 3 = 332919

Therefore, the lowest common multiple of 521,213,639 is 332919.

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 213 x 639 = 70911747

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

213 : 1, 3, 71, 213

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,213,639, is 1.

Now, the common factors can be found like this.

521:521

213:3x 71

639:3x 3x 71

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

3x 71 = 213

Therefore, the value for common factors is 213.

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 = 70911747/(1x213)

LCM = 70911747/213

LCM = 332919

Thus, we can understand that the LCM of 521,213,639 is 332919.

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

• LCM of 563, 466, 980
• LCM of 139, 430, 550
