Given numbers are 1,637,921,429

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

The LCM of 1,637,921,429 is 6453447.

Find LCM of 1,637,921,429 with Prime Factorization

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

3 x 13 x 1 x 49 x 307 x 11 = 6453447

Therefore, the lowest common multiple of 1,637,921,429 is 6453447.

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.

1 x 637 x 921 x 429 = 251684433

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.

1 : 1

637 : 1, 7, 13, 49, 91, 637

921 : 1, 3, 307, 921

429 : 1, 3, 11, 13, 33, 39, 143, 429

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,637,921,429, is 1.

Now, the common factors can be found like this.

1:

637:7x 7x 13

921:3x 307

429:3x 11x 13

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

3x 13 = 39

Therefore, the value for common factors is 39.

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 = 251684433/(1x39)

LCM = 251684433/39

LCM = 6453447

Thus, we can understand that the LCM of 1,637,921,429 is 6453447.

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

• LCM of 6, 811, 790, 433
