Given numbers are 215,234,172,287

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

The LCM of 215,234,172,287 is 28877940.

Find LCM of 215,234,172,287 with Prime Factorization

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

2 x 43 x 5 x 117 x 2 x 287 = 28877940

Therefore, the lowest common multiple of 215,234,172,287 is 28877940.

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.

215 x 234 x 172 x 287 = 2483502840

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.

215 : 1, 5, 43, 215

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

172 : 1, 2, 4, 43, 86, 172

287 : 1, 7, 41, 287

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,234,172,287, is 1.

Now, the common factors can be found like this.

215:5x 43

234:2x 3x 3x 13

172:2x 2x 43

287:7x 41

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

2x 43 = 86

Therefore, the value for common factors is 86.

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 = 2483502840/(1x86)

LCM = 2483502840/86

LCM = 28877940

Thus, we can understand that the LCM of 215,234,172,287 is 28877940.
