Given numbers are 861,557,287

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

The LCM of 861,557,287 is 479577.

Find LCM of 861,557,287 with Prime Factorization

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

7 x 41 x 3 x 557 x 1 = 479577

Therefore, the lowest common multiple of 861,557,287 is 479577.

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.

861 x 557 x 287 = 137638599

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

557 : 1, 557

287 : 1, 7, 41, 287

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,557,287, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

557:557

287:7x 41

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7x 41 = 287

Therefore, the value for common factors is 287.

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 = 137638599/(1x287)

LCM = 137638599/287

LCM = 479577

Thus, we can understand that the LCM of 861,557,287 is 479577.

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

• LCM of 649, 433, 479
• LCM of 993, 619, 645
