Given numbers are 5451,5721

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

The LCM of 5451,5721 is 10395057.

Find LCM of 5451,5721 with Prime Factorization

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

3 x 1817 x 1907 = 10395057

Therefore, the lowest common multiple of 5451,5721 is 10395057.

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.

5451 x 5721 = 31185171

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.

5451 : 1, 3, 23, 69, 79, 237, 1817, 5451

5721 : 1, 3, 1907, 5721

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 5451,5721, is 3.

Now, the common factors can be found like this.

5451:3x 23x 79

5721:3x 1907

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 = 31185171/(3x1)

LCM = 31185171/3

LCM = 10395057

Thus, we can understand that the LCM of 5451,5721 is 10395057.

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

• LCM of 1094, 7568
