Given numbers are 517,253,173,621

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

The LCM of 517,253,173,621 is 55542861.

Find LCM of 517,253,173,621 with Prime Factorization

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

11 x 23 x 47 x 1 x 173 x 27 = 55542861

Therefore, the lowest common multiple of 517,253,173,621 is 55542861.

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.

517 x 253 x 173 x 621 = 14052343833

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.

517 : 1, 11, 47, 517

253 : 1, 11, 23, 253

173 : 1, 173

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,253,173,621, is 1.

Now, the common factors can be found like this.

517:11x 47

253:11x 23

173:173

621:3x 3x 3x 23

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

11x 23 = 253

Therefore, the value for common factors is 253.

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 = 14052343833/(1x253)

LCM = 14052343833/253

LCM = 55542861

Thus, we can understand that the LCM of 517,253,173,621 is 55542861.
