Given numbers are 687,501,721

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

The LCM of 687,501,721 is 82719609.

Find LCM of 687,501,721 with Prime Factorization

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

3 x 229 x 167 x 721 = 82719609

Therefore, the lowest common multiple of 687,501,721 is 82719609.

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.

687 x 501 x 721 = 248158827

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.

687 : 1, 3, 229, 687

501 : 1, 3, 167, 501

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,501,721, is 1.

Now, the common factors can be found like this.

687:3x 229

501:3x 167

721:7x 103

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 = 248158827/(1x3)

LCM = 248158827/3

LCM = 82719609

Thus, we can understand that the LCM of 687,501,721 is 82719609.

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

• LCM of 957, 849, 935
• LCM of 201, 640, 446
