Given numbers are 205,464,253,861

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

The LCM of 205,464,253,861 is 505372560.

Find LCM of 205,464,253,861 with Prime Factorization

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

41 x 5 x 464 x 253 x 21 = 505372560

Therefore, the lowest common multiple of 205,464,253,861 is 505372560.

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.

205 x 464 x 253 x 861 = 20720274960

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.

205 : 1, 5, 41, 205

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

253 : 1, 11, 23, 253

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 205,464,253,861, is 1.

Now, the common factors can be found like this.

205:5x 41

464:2x 2x 2x 2x 29

253:11x 23

861:3x 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.

41 = 41

Therefore, the value for common factors is 41.

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 = 20720274960/(1x41)

LCM = 20720274960/41

LCM = 505372560

Thus, we can understand that the LCM of 205,464,253,861 is 505372560.
