Given numbers are 821,771,753

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

The LCM of 821,771,753 is 158880741.

Find LCM of 821,771,753 with Prime Factorization

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

3 x 821 x 257 x 251 = 158880741

Therefore, the lowest common multiple of 821,771,753 is 158880741.

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.

821 x 771 x 753 = 476642223

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.

821 : 1, 821

771 : 1, 3, 257, 771

753 : 1, 3, 251, 753

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,771,753, is 1.

Now, the common factors can be found like this.

821:821

771:3x 257

753:3x 251

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 = 476642223/(1x3)

LCM = 476642223/3

LCM = 158880741

Thus, we can understand that the LCM of 821,771,753 is 158880741.

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

• LCM of 826, 102, 477
