Given numbers are 916,458,819,421

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

The LCM of 916,458,819,421 is 315835884.

Find LCM of 916,458,819,421 with Prime Factorization

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

2 x 229 x 2 x 1 x 819 x 421 = 315835884

Therefore, the lowest common multiple of 916,458,819,421 is 315835884.

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.

916 x 458 x 819 x 421 = 144652834872

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.

916 : 1, 2, 4, 229, 458, 916

458 : 1, 2, 229, 458

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,458,819,421, is 1.

Now, the common factors can be found like this.

916:2x 2x 229

458:2x 229

819:3x 3x 7x 13

421:421

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

2x 229 = 458

Therefore, the value for common factors is 458.

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 = 144652834872/(1x458)

LCM = 144652834872/458

LCM = 315835884

Thus, we can understand that the LCM of 916,458,819,421 is 315835884.
