Given numbers are 81,694,345

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

The LCM of 81,694,345 is 6464610.

Find LCM of 81,694,345 with Prime Factorization

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

3 x 27 x 694 x 115 = 6464610

Therefore, the lowest common multiple of 81,694,345 is 6464610.

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.

81 x 694 x 345 = 19393830

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.

81 : 1, 3, 9, 27, 81

694 : 1, 2, 347, 694

345 : 1, 3, 5, 15, 23, 69, 115, 345

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 81,694,345, is 1.

Now, the common factors can be found like this.

81:3x 3x 3x 3

694:2x 347

345:3x 5x 23

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 = 19393830/(1x3)

LCM = 19393830/3

LCM = 6464610

Thus, we can understand that the LCM of 81,694,345 is 6464610.

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

• LCM of 16, 363, 622
• LCM of 88, 682, 520
