Given numbers are 821,155,845,110

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

The LCM of 821,155,845,110 is 473134090.

Find LCM of 821,155,845,110 with Prime Factorization

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

5 x 821 x 31 x 169 x 22 = 473134090

Therefore, the lowest common multiple of 821,155,845,110 is 473134090.

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 155 x 845 x 110 = 11828352250

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

155 : 1, 5, 31, 155

845 : 1, 5, 13, 65, 169, 845

110 : 1, 2, 5, 10, 11, 22, 55, 110

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,155,845,110, is 1.

Now, the common factors can be found like this.

821:821

155:5x 31

845:5x 13x 13

110:2x 5x 11

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 11828352250/(1x25)

LCM = 11828352250/25

LCM = 473134090

Thus, we can understand that the LCM of 821,155,845,110 is 473134090.
