Given numbers are 1455,7881

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

The LCM of 1455,7881 is 3822285.

Find LCM of 1455,7881 with Prime Factorization

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

3 x 485 x 2627 = 3822285

Therefore, the lowest common multiple of 1455,7881 is 3822285.

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.

1455 x 7881 = 11466855

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.

1455 : 1, 3, 5, 15, 97, 291, 485, 1455

7881 : 1, 3, 37, 71, 111, 213, 2627, 7881

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1455,7881, is 3.

Now, the common factors can be found like this.

1455:3x 5x 97

7881:3x 37x 71

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 = 11466855/(3x1)

LCM = 11466855/3

LCM = 3822285

Thus, we can understand that the LCM of 1455,7881 is 3822285.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 6977, 6983
