Given numbers are 3951,1515

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

The LCM of 3951,1515 is 1995255.

Find LCM of 3951,1515 with Prime Factorization

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

3 x 1317 x 505 = 1995255

Therefore, the lowest common multiple of 3951,1515 is 1995255.

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.

3951 x 1515 = 5985765

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.

3951 : 1, 3, 9, 439, 1317, 3951

1515 : 1, 3, 5, 15, 101, 303, 505, 1515

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3951,1515, is 3.

Now, the common factors can be found like this.

3951:3x 3x 439

1515:3x 5x 101

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 = 5985765/(3x1)

LCM = 5985765/3

LCM = 1995255

Thus, we can understand that the LCM of 3951,1515 is 1995255.
