Given numbers are 15,11,22,71,418

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

The LCM of 15,11,22,71,418 is 445170.

Find LCM of 15,11,22,71,418 with Prime Factorization

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

2 x 11 x 15 x 1 x 1 x 71 x 19 = 445170

Therefore, the lowest common multiple of 15,11,22,71,418 is 445170.

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.

15 x 11 x 22 x 71 x 418 = 107731140

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.

15 : 1, 3, 5, 15

11 : 1, 11

22 : 1, 2, 11, 22

71 : 1, 71

418 : 1, 2, 11, 19, 22, 38, 209, 418

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 15,11,22,71,418, is 1.

Now, the common factors can be found like this.

15:3x 5

11:11

22:2x 11

71:71

418:2x 11x 19

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

2x 11x 11 = 242

Therefore, the value for common factors is 242.

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 = 107731140/(1x242)

LCM = 107731140/242

LCM = 445170

Thus, we can understand that the LCM of 15,11,22,71,418 is 445170.
