Given numbers are 905,415,340,215

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

The LCM of 905,415,340,215 is 219636260.

Find LCM of 905,415,340,215 with Prime Factorization

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

5 x 181 x 83 x 68 x 43 = 219636260

Therefore, the lowest common multiple of 905,415,340,215 is 219636260.

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.

905 x 415 x 340 x 215 = 27454532500

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.

905 : 1, 5, 181, 905

415 : 1, 5, 83, 415

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

215 : 1, 5, 43, 215

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,415,340,215, is 5.

Now, the common factors can be found like this.

905:5x 181

415:5x 83

340:2x 2x 5x 17

215:5x 43

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 27454532500/(5x25)

LCM = 27454532500/125

LCM = 219636260

Thus, we can understand that the LCM of 905,415,340,215 is 219636260.
