Given numbers are 605,140,920,258,458

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

The LCM of 605,140,920,258,458 is 23019528840.

Find LCM of 605,140,920,258,458 with Prime Factorization

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

2 x 2 x 5 x 121 x 7 x 46 x 129 x 229 = 23019528840

Therefore, the lowest common multiple of 605,140,920,258,458 is 23019528840.

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.

605 x 140 x 920 x 258 x 458 = 9207811536000

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.

605 : 1, 5, 11, 55, 121, 605

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

258 : 1, 2, 3, 6, 43, 86, 129, 258

458 : 1, 2, 229, 458

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,140,920,258,458, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

140:2x 2x 5x 7

920:2x 2x 2x 5x 23

258:2x 3x 43

458:2x 229

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

2x 2x 2x 2x 5x 5 = 400

Therefore, the value for common factors is 400.

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 = 9207811536000/(1x400)

LCM = 9207811536000/400

LCM = 23019528840

Thus, we can understand that the LCM of 605,140,920,258,458 is 23019528840.
