Given numbers are 13,39,86,58,812

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

The LCM of 13,39,86,58,812 is 1361724.

Find LCM of 13,39,86,58,812 with Prime Factorization

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

2 x 13 x 29 x 1 x 3 x 43 x 1 x 14 = 1361724

Therefore, the lowest common multiple of 13,39,86,58,812 is 1361724.

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.

13 x 39 x 86 x 58 x 812 = 2053479792

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.

13 : 1, 13

39 : 1, 3, 13, 39

86 : 1, 2, 43, 86

58 : 1, 2, 29, 58

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 13,39,86,58,812, is 1.

Now, the common factors can be found like this.

13:13

39:3x 13

86:2x 43

58:2x 29

812:2x 2x 7x 29

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 13x 29 = 1508

Therefore, the value for common factors is 1508.

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 = 2053479792/(1x1508)

LCM = 2053479792/1508

LCM = 1361724

Thus, we can understand that the LCM of 13,39,86,58,812 is 1361724.
