Given numbers are 1755,3921

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

The LCM of 1755,3921 is 2293785.

Find LCM of 1755,3921 with Prime Factorization

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

3 x 585 x 1307 = 2293785

Therefore, the lowest common multiple of 1755,3921 is 2293785.

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.

1755 x 3921 = 6881355

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.

1755 : 1, 3, 5, 9, 13, 15, 27, 39, 45, 65, 117, 135, 195, 351, 585, 1755

3921 : 1, 3, 1307, 3921

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1755,3921, is 3.

Now, the common factors can be found like this.

1755:3x 3x 3x 5x 13

3921:3x 1307

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 = 6881355/(3x1)

LCM = 6881355/3

LCM = 2293785

Thus, we can understand that the LCM of 1755,3921 is 2293785.

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

• LCM of 4746, 8058
• LCM of 1570, 3087
