Given numbers are 186,221,155

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

The LCM of 186,221,155 is 205530.

Find LCM of 186,221,155 with Prime Factorization

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

31 x 6 x 221 x 5 = 205530

Therefore, the lowest common multiple of 186,221,155 is 205530.

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.

186 x 221 x 155 = 6371430

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.

186 : 1, 2, 3, 6, 31, 62, 93, 186

221 : 1, 13, 17, 221

155 : 1, 5, 31, 155

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 186,221,155, is 1.

Now, the common factors can be found like this.

186:2x 3x 31

221:13x 17

155:5x 31

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

31 = 31

Therefore, the value for common factors is 31.

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 = 6371430/(1x31)

LCM = 6371430/31

LCM = 205530

Thus, we can understand that the LCM of 186,221,155 is 205530.

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

• LCM of 887, 539, 677
• LCM of 260, 490, 134
