Given numbers are 221,923,247

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

The LCM of 221,923,247 is 298129.

Find LCM of 221,923,247 with Prime Factorization

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

13 x 17 x 71 x 19 = 298129

Therefore, the lowest common multiple of 221,923,247 is 298129.

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.

221 x 923 x 247 = 50383801

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.

221 : 1, 13, 17, 221

923 : 1, 13, 71, 923

247 : 1, 13, 19, 247

13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,923,247, is 13.

Now, the common factors can be found like this.

221:13x 17

923:13x 71

247:13x 19

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

13 = 13

Therefore, the value for common factors is 13.

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 = 50383801/(13x13)

LCM = 50383801/169

LCM = 298129

Thus, we can understand that the LCM of 221,923,247 is 298129.

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

• LCM of 523, 247, 159
