Given numbers are 835,350,805,21

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

The LCM of 835,350,805,21 is 4033050.

Find LCM of 835,350,805,21 with Prime Factorization

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

5 x 7 x 167 x 10 x 23 x 3 = 4033050

Therefore, the lowest common multiple of 835,350,805,21 is 4033050.

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.

835 x 350 x 805 x 21 = 4940486250

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.

835 : 1, 5, 167, 835

350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350

805 : 1, 5, 7, 23, 35, 115, 161, 805

21 : 1, 3, 7, 21

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 835,350,805,21, is 1.

Now, the common factors can be found like this.

835:5x 167

350:2x 5x 5x 7

805:5x 7x 23

21:3x 7

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

5x 5x 7x 7 = 1225

Therefore, the value for common factors is 1225.

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 = 4940486250/(1x1225)

LCM = 4940486250/1225

LCM = 4033050

Thus, we can understand that the LCM of 835,350,805,21 is 4033050.
