Given numbers are 821,195,806,104

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

The LCM of 821,195,806,104 is 39703560.

Find LCM of 821,195,806,104 with Prime Factorization

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

2 x 13 x 821 x 15 x 31 x 4 = 39703560

Therefore, the lowest common multiple of 821,195,806,104 is 39703560.

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 195 x 806 x 104 = 13419803280

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

195 : 1, 3, 5, 13, 15, 39, 65, 195

806 : 1, 2, 13, 26, 31, 62, 403, 806

104 : 1, 2, 4, 8, 13, 26, 52, 104

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,195,806,104, is 1.

Now, the common factors can be found like this.

821:821

195:3x 5x 13

806:2x 13x 31

104:2x 2x 2x 13

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

2x 13x 13 = 338

Therefore, the value for common factors is 338.

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 = 13419803280/(1x338)

LCM = 13419803280/338

LCM = 39703560

Thus, we can understand that the LCM of 821,195,806,104 is 39703560.
