Given numbers are 79,15,87,43,398

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

The LCM of 79,15,87,43,398 is 588122610.

Find LCM of 79,15,87,43,398 with Prime Factorization

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

3 x 79 x 5 x 29 x 43 x 398 = 588122610

Therefore, the lowest common multiple of 79,15,87,43,398 is 588122610.

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.

79 x 15 x 87 x 43 x 398 = 1764367830

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.

79 : 1, 79

15 : 1, 3, 5, 15

87 : 1, 3, 29, 87

43 : 1, 43

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 79,15,87,43,398, is 1.

Now, the common factors can be found like this.

79:79

15:3x 5

87:3x 29

43:43

398:2x 199

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

3 = 3

Therefore, the value for common factors is 3.

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 = 1764367830/(1x3)

LCM = 1764367830/3

LCM = 588122610

Thus, we can understand that the LCM of 79,15,87,43,398 is 588122610.
