Calculate the LCM of 221,198,234

Given numbers are 221,198,234

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

The LCM of 221,198,234 is 43758.

Find LCM of 221,198,234 with Prime Factorization


2 221, 198, 234
3 221, 99, 117
3 221, 33, 39
13 221, 11, 13
17, 11, 1

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

2 x 3 x 3 x 13 x 17 x 11 x 1 = 43758

Therefore, the lowest common multiple of 221,198,234 is 43758.

LCM Formula to Find Lowest Common Multiple of 221,198,234

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 198 x 234 = 10239372

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

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,198,234, is 1.

Now, the common factors can be found like this.

221:13x 17

198:2x 3x 3x 11

234:2x 3x 3x 13

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

2x 3x 3x 13 = 234

Therefore, the value for common factors is 234.

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 = 10239372/(1x234)

LCM = 10239372/234

LCM = 43758

Thus, we can understand that the LCM of 221,198,234 is 43758.
