Given numbers are 245,215,173,865

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

The LCM of 245,215,173,865 is 1822555.

Find LCM of 245,215,173,865 with Prime Factorization

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

5 x 173 x 49 x 43 x 1 x 1 = 1822555

Therefore, the lowest common multiple of 245,215,173,865 is 1822555.

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.

245 x 215 x 173 x 865 = 7882550375

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.

245 : 1, 5, 7, 35, 49, 245

215 : 1, 5, 43, 215

173 : 1, 173

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 245,215,173,865, is 1.

Now, the common factors can be found like this.

245:5x 7x 7

215:5x 43

173:173

865:5x 173

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

5x 5x 173 = 4325

Therefore, the value for common factors is 4325.

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 = 7882550375/(1x4325)

LCM = 7882550375/4325

LCM = 1822555

Thus, we can understand that the LCM of 245,215,173,865 is 1822555.
