Given numbers are 455,27,715

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

The LCM of 455,27,715 is 135135.

Find LCM of 455,27,715 with Prime Factorization

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

5 x 13 x 7 x 27 x 11 = 135135

Therefore, the lowest common multiple of 455,27,715 is 135135.

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.

455 x 27 x 715 = 8783775

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

27 : 1, 3, 9, 27

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,27,715, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

27:3x 3x 3

715:5x 11x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

5x 13 = 65

Therefore, the value for common factors is 65.

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 = 8783775/(1x65)

LCM = 8783775/65

LCM = 135135

Thus, we can understand that the LCM of 455,27,715 is 135135.

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

• LCM of 873, 36, 126
