Given numbers are 8490,2390

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

The LCM of 8490,2390 is 2029110.

Find LCM of 8490,2390 with Prime Factorization

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

2 x 5 x 849 x 239 = 2029110

Therefore, the lowest common multiple of 8490,2390 is 2029110.

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.

8490 x 2390 = 20291100

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.

8490 : 1, 2, 3, 5, 6, 10, 15, 30, 283, 566, 849, 1415, 1698, 2830, 4245, 8490

2390 : 1, 2, 5, 10, 239, 478, 1195, 2390

10 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8490,2390, is 10.

Now, the common factors can be found like this.

8490:2x 3x 5x 283

2390:2x 5x 239

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 = 20291100/(10x1)

LCM = 20291100/10

LCM = 2029110

Thus, we can understand that the LCM of 8490,2390 is 2029110.
