Given numbers are 471,540,821

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

The LCM of 471,540,821 is 69604380.

Find LCM of 471,540,821 with Prime Factorization

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

3 x 157 x 180 x 821 = 69604380

Therefore, the lowest common multiple of 471,540,821 is 69604380.

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.

471 x 540 x 821 = 208813140

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.

471 : 1, 3, 157, 471

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,540,821, is 1.

Now, the common factors can be found like this.

471:3x 157

540:2x 2x 3x 3x 3x 5

821:821

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 = 208813140/(1x3)

LCM = 208813140/3

LCM = 69604380

Thus, we can understand that the LCM of 471,540,821 is 69604380.

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

• LCM of 954, 267, 397
