Given numbers are 31,411,639

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

The LCM of 31,411,639 is 2713833.

Find LCM of 31,411,639 with Prime Factorization

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

3 x 31 x 137 x 213 = 2713833

Therefore, the lowest common multiple of 31,411,639 is 2713833.

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.

31 x 411 x 639 = 8141499

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.

31 : 1, 31

411 : 1, 3, 137, 411

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 31,411,639, is 1.

Now, the common factors can be found like this.

31:31

411:3x 137

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.

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 = 8141499/(1x3)

LCM = 8141499/3

LCM = 2713833

Thus, we can understand that the LCM of 31,411,639 is 2713833.

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

• LCM of 10, 293, 952
• LCM of 25, 835, 887
