Given numbers are 2649,2139

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

The LCM of 2649,2139 is 1888737.

Find LCM of 2649,2139 with Prime Factorization

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

3 x 883 x 713 = 1888737

Therefore, the lowest common multiple of 2649,2139 is 1888737.

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.

2649 x 2139 = 5666211

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.

2649 : 1, 3, 883, 2649

2139 : 1, 3, 23, 31, 69, 93, 713, 2139

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2649,2139, is 3.

Now, the common factors can be found like this.

2649:3x 883

2139:3x 23x 31

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 = 5666211/(3x1)

LCM = 5666211/3

LCM = 1888737

Thus, we can understand that the LCM of 2649,2139 is 1888737.
