Given numbers are 209,81,931

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

The LCM of 209,81,931 is 829521.

Find LCM of 209,81,931 with Prime Factorization

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

19 x 11 x 81 x 49 = 829521

Therefore, the lowest common multiple of 209,81,931 is 829521.

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.

209 x 81 x 931 = 15760899

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.

209 : 1, 11, 19, 209

81 : 1, 3, 9, 27, 81

931 : 1, 7, 19, 49, 133, 931

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,81,931, is 1.

Now, the common factors can be found like this.

209:11x 19

81:3x 3x 3x 3

931:7x 7x 19

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

19 = 19

Therefore, the value for common factors is 19.

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 = 15760899/(1x19)

LCM = 15760899/19

LCM = 829521

Thus, we can understand that the LCM of 209,81,931 is 829521.

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

• LCM of 767, 74, 630
• LCM of 671, 33, 765
