Given numbers are 7821,3513

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

The LCM of 7821,3513 is 9158391.

Find LCM of 7821,3513 with Prime Factorization

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

3 x 2607 x 1171 = 9158391

Therefore, the lowest common multiple of 7821,3513 is 9158391.

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.

7821 x 3513 = 27475173

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.

7821 : 1, 3, 9, 11, 33, 79, 99, 237, 711, 869, 2607, 7821

3513 : 1, 3, 1171, 3513

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7821,3513, is 3.

Now, the common factors can be found like this.

7821:3x 3x 11x 79

3513:3x 1171

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 = 27475173/(3x1)

LCM = 27475173/3

LCM = 9158391

Thus, we can understand that the LCM of 7821,3513 is 9158391.

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

• LCM of 5281, 3202
• LCM of 2584, 4674
