Given numbers are 661,349,458,642,458

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

The LCM of 661,349,458,642,458 is 33915435402.

Find LCM of 661,349,458,642,458 with Prime Factorization

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

2 x 229 x 661 x 349 x 1 x 321 x 1 = 33915435402

Therefore, the lowest common multiple of 661,349,458,642,458 is 33915435402.

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.

661 x 349 x 458 x 642 x 458 = 31066538828232

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.

661 : 1, 661

349 : 1, 349

458 : 1, 2, 229, 458

642 : 1, 2, 3, 6, 107, 214, 321, 642

458 : 1, 2, 229, 458

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,349,458,642,458, is 1.

Now, the common factors can be found like this.

661:661

349:349

458:2x 229

642:2x 3x 107

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 229 = 916

Therefore, the value for common factors is 916.

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 = 31066538828232/(1x916)

LCM = 31066538828232/916

LCM = 33915435402

Thus, we can understand that the LCM of 661,349,458,642,458 is 33915435402.
