Given numbers are 685,68,826

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

The LCM of 685,68,826 is 19237540.

Find LCM of 685,68,826 with Prime Factorization

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

2 x 685 x 34 x 413 = 19237540

Therefore, the lowest common multiple of 685,68,826 is 19237540.

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.

685 x 68 x 826 = 38475080

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.

685 : 1, 5, 137, 685

68 : 1, 2, 4, 17, 34, 68

826 : 1, 2, 7, 14, 59, 118, 413, 826

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,68,826, is 1.

Now, the common factors can be found like this.

685:5x 137

68:2x 2x 17

826:2x 7x 59

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

2 = 2

Therefore, the value for common factors is 2.

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 = 38475080/(1x2)

LCM = 38475080/2

LCM = 19237540

Thus, we can understand that the LCM of 685,68,826 is 19237540.

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

• LCM of 470, 57, 774
• LCM of 418, 78, 386
