Given numbers are 1881,7146

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

The LCM of 1881,7146 is 1493514.

Find LCM of 1881,7146 with Prime Factorization

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

3 x 3 x 209 x 794 = 1493514

Therefore, the lowest common multiple of 1881,7146 is 1493514.

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.

1881 x 7146 = 13441626

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.

1881 : 1, 3, 9, 11, 19, 33, 57, 99, 171, 209, 627, 1881

7146 : 1, 2, 3, 6, 9, 18, 397, 794, 1191, 2382, 3573, 7146

9 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1881,7146, is 9.

Now, the common factors can be found like this.

1881:3x 3x 11x 19

7146:2x 3x 3x 397

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

= 1

Therefore, the value for common factors is 1.

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 = 13441626/(9x1)

LCM = 13441626/9

LCM = 1493514

Thus, we can understand that the LCM of 1881,7146 is 1493514.

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

• LCM of 9385, 7562
• LCM of 7703, 4754
