Given numbers are 821,319,781

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

The LCM of 821,319,781 is 18594829.

Find LCM of 821,319,781 with Prime Factorization

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

11 x 821 x 29 x 71 = 18594829

Therefore, the lowest common multiple of 821,319,781 is 18594829.

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 319 x 781 = 204543119

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

319 : 1, 11, 29, 319

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,319,781, is 1.

Now, the common factors can be found like this.

821:821

319:11x 29

781:11x 71

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

11 = 11

Therefore, the value for common factors is 11.

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 = 204543119/(1x11)

LCM = 204543119/11

LCM = 18594829

Thus, we can understand that the LCM of 821,319,781 is 18594829.

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

• LCM of 368, 368, 711
