Given numbers are 1646,6838

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

The LCM of 1646,6838 is 5627674.

Find LCM of 1646,6838 with Prime Factorization

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

2 x 823 x 3419 = 5627674

Therefore, the lowest common multiple of 1646,6838 is 5627674.

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.

1646 x 6838 = 11255348

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.

1646 : 1, 2, 823, 1646

6838 : 1, 2, 13, 26, 263, 526, 3419, 6838

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1646,6838, is 2.

Now, the common factors can be found like this.

1646:2x 823

6838:2x 13x 263

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

= 1

Therefore, the value for common factors is 1.

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 = 11255348/(2x1)

LCM = 11255348/2

LCM = 5627674

Thus, we can understand that the LCM of 1646,6838 is 5627674.

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

• LCM of 3349, 9458
• LCM of 2431, 1589
