Given numbers are 689,22,822

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

The LCM of 689,22,822 is 6229938.

Find LCM of 689,22,822 with Prime Factorization

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

2 x 689 x 11 x 411 = 6229938

Therefore, the lowest common multiple of 689,22,822 is 6229938.

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.

689 x 22 x 822 = 12459876

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.

689 : 1, 13, 53, 689

22 : 1, 2, 11, 22

822 : 1, 2, 3, 6, 137, 274, 411, 822

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,22,822, is 1.

Now, the common factors can be found like this.

689:13x 53

22:2x 11

822:2x 3x 137

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 = 12459876/(1x2)

LCM = 12459876/2

LCM = 6229938

Thus, we can understand that the LCM of 689,22,822 is 6229938.

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

• LCM of 896, 33, 629
• LCM of 743, 41, 581
