Given numbers are 171,28,663

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

The LCM of 171,28,663 is 1058148.

Find LCM of 171,28,663 with Prime Factorization

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

3 x 57 x 28 x 221 = 1058148

Therefore, the lowest common multiple of 171,28,663 is 1058148.

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.

171 x 28 x 663 = 3174444

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.

171 : 1, 3, 9, 19, 57, 171

28 : 1, 2, 4, 7, 14, 28

663 : 1, 3, 13, 17, 39, 51, 221, 663

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,28,663, is 1.

Now, the common factors can be found like this.

171:3x 3x 19

28:2x 2x 7

663:3x 13x 17

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

3 = 3

Therefore, the value for common factors is 3.

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 = 3174444/(1x3)

LCM = 3174444/3

LCM = 1058148

Thus, we can understand that the LCM of 171,28,663 is 1058148.

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

• LCM of 312, 61, 523
• LCM of 455, 63, 822
