Given numbers are 431,426,921

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

The LCM of 431,426,921 is 56367042.

Find LCM of 431,426,921 with Prime Factorization

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

3 x 431 x 142 x 307 = 56367042

Therefore, the lowest common multiple of 431,426,921 is 56367042.

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.

431 x 426 x 921 = 169101126

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.

431 : 1, 431

426 : 1, 2, 3, 6, 71, 142, 213, 426

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,426,921, is 1.

Now, the common factors can be found like this.

431:431

426:2x 3x 71

921:3x 307

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 = 169101126/(1x3)

LCM = 169101126/3

LCM = 56367042

Thus, we can understand that the LCM of 431,426,921 is 56367042.

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

• LCM of 842, 387, 979
• LCM of 527, 164, 526
• LCM of 996, 464, 841
