Given numbers are 2146,7690

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

The LCM of 2146,7690 is 8251370.

Find LCM of 2146,7690 with Prime Factorization

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

2 x 1073 x 3845 = 8251370

Therefore, the lowest common multiple of 2146,7690 is 8251370.

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.

2146 x 7690 = 16502740

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.

2146 : 1, 2, 29, 37, 58, 74, 1073, 2146

7690 : 1, 2, 5, 10, 769, 1538, 3845, 7690

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2146,7690, is 2.

Now, the common factors can be found like this.

2146:2x 29x 37

7690:2x 5x 769

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 = 16502740/(2x1)

LCM = 16502740/2

LCM = 8251370

Thus, we can understand that the LCM of 2146,7690 is 8251370.
