Given numbers are 458,580,347,686,661

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

The LCM of 458,580,347,686,661 is 10449332054420.

Find LCM of 458,580,347,686,661 with Prime Factorization

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

2 x 229 x 290 x 347 x 343 x 661 = 10449332054420

Therefore, the lowest common multiple of 458,580,347,686,661 is 10449332054420.

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.

458 x 580 x 347 x 686 x 661 = 41797328217680

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.

458 : 1, 2, 229, 458

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

347 : 1, 347

686 : 1, 2, 7, 14, 49, 98, 343, 686

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 458,580,347,686,661, is 1.

Now, the common factors can be found like this.

458:2x 229

580:2x 2x 5x 29

347:347

686:2x 7x 7x 7

661:661

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 41797328217680/(1x4)

LCM = 41797328217680/4

LCM = 10449332054420

Thus, we can understand that the LCM of 458,580,347,686,661 is 10449332054420.
