Given numbers are 4280,2105

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

The LCM of 4280,2105 is 1801880.

Find LCM of 4280,2105 with Prime Factorization

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

5 x 856 x 421 = 1801880

Therefore, the lowest common multiple of 4280,2105 is 1801880.

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.

4280 x 2105 = 9009400

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.

4280 : 1, 2, 4, 5, 8, 10, 20, 40, 107, 214, 428, 535, 856, 1070, 2140, 4280

2105 : 1, 5, 421, 2105

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4280,2105, is 5.

Now, the common factors can be found like this.

4280:2x 2x 2x 5x 107

2105:5x 421

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 = 9009400/(5x1)

LCM = 9009400/5

LCM = 1801880

Thus, we can understand that the LCM of 4280,2105 is 1801880.
