Given numbers are 36,20,845

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

The LCM of 36,20,845 is 30420.

Find LCM of 36,20,845 with Prime Factorization

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

2 x 2 x 5 x 9 x 1 x 169 = 30420

Therefore, the lowest common multiple of 36,20,845 is 30420.

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.

36 x 20 x 845 = 608400

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.

36 : 1, 2, 3, 4, 6, 9, 12, 18, 36

20 : 1, 2, 4, 5, 10, 20

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 36,20,845, is 1.

Now, the common factors can be found like this.

36:2x 2x 3x 3

20:2x 2x 5

845:5x 13x 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 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 608400/(1x20)

LCM = 608400/20

LCM = 30420

Thus, we can understand that the LCM of 36,20,845 is 30420.
