Given numbers are 18,71,87,598

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

The LCM of 18,71,87,598 is 11081538.

Find LCM of 18,71,87,598 with Prime Factorization

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

2 x 3 x 3 x 71 x 29 x 299 = 11081538

Therefore, the lowest common multiple of 18,71,87,598 is 11081538.

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.

18 x 71 x 87 x 598 = 66489228

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.

18 : 1, 2, 3, 6, 9, 18

71 : 1, 71

87 : 1, 3, 29, 87

598 : 1, 2, 13, 23, 26, 46, 299, 598

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 18,71,87,598, is 1.

Now, the common factors can be found like this.

18:2x 3x 3

71:71

87:3x 29

598:2x 13x 23

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 66489228/(1x6)

LCM = 66489228/6

LCM = 11081538

Thus, we can understand that the LCM of 18,71,87,598 is 11081538.
