Given numbers are 238,218,661

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

The LCM of 238,218,661 is 17147662.

Find LCM of 238,218,661 with Prime Factorization

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

2 x 119 x 109 x 661 = 17147662

Therefore, the lowest common multiple of 238,218,661 is 17147662.

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.

238 x 218 x 661 = 34295324

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.

238 : 1, 2, 7, 14, 17, 34, 119, 238

218 : 1, 2, 109, 218

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,218,661, is 1.

Now, the common factors can be found like this.

238:2x 7x 17

218:2x 109

661:661

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

2 = 2

Therefore, the value for common factors is 2.

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 = 34295324/(1x2)

LCM = 34295324/2

LCM = 17147662

Thus, we can understand that the LCM of 238,218,661 is 17147662.

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

• LCM of 734, 556, 842
• LCM of 828, 216, 306
