Given numbers are 231,103,921

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

The LCM of 231,103,921 is 7304451.

Find LCM of 231,103,921 with Prime Factorization

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

3 x 77 x 103 x 307 = 7304451

Therefore, the lowest common multiple of 231,103,921 is 7304451.

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.

231 x 103 x 921 = 21913353

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.

231 : 1, 3, 7, 11, 21, 33, 77, 231

103 : 1, 103

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,103,921, is 1.

Now, the common factors can be found like this.

231:3x 7x 11

103:103

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 = 21913353/(1x3)

LCM = 21913353/3

LCM = 7304451

Thus, we can understand that the LCM of 231,103,921 is 7304451.

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

• LCM of 752, 358, 567
• LCM of 378, 992, 201
