Given numbers are 821,859,538,478,993

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

The LCM of 821,859,538,478,993 is 90046273810314.

Find LCM of 821,859,538,478,993 with Prime Factorization

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

2 x 821 x 859 x 269 x 239 x 993 = 90046273810314

Therefore, the lowest common multiple of 821,859,538,478,993 is 90046273810314.

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.

821 x 859 x 538 x 478 x 993 = 180092547620628

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.

821 : 1, 821

859 : 1, 859

538 : 1, 2, 269, 538

478 : 1, 2, 239, 478

993 : 1, 3, 331, 993

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,859,538,478,993, is 1.

Now, the common factors can be found like this.

821:821

859:859

538:2x 269

478:2x 239

993:3x 331

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

2 = 2

Therefore, the value for common factors is 2.

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 = 180092547620628/(1x2)

LCM = 180092547620628/2

LCM = 90046273810314

Thus, we can understand that the LCM of 821,859,538,478,993 is 90046273810314.
