Given numbers are 815,161,340,135

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

The LCM of 815,161,340,135 is 240910740.

Find LCM of 815,161,340,135 with Prime Factorization

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

5 x 163 x 161 x 68 x 27 = 240910740

Therefore, the lowest common multiple of 815,161,340,135 is 240910740.

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.

815 x 161 x 340 x 135 = 6022768500

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.

815 : 1, 5, 163, 815

161 : 1, 7, 23, 161

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

135 : 1, 3, 5, 9, 15, 27, 45, 135

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,161,340,135, is 1.

Now, the common factors can be found like this.

815:5x 163

161:7x 23

340:2x 2x 5x 17

135:3x 3x 3x 5

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 6022768500/(1x25)

LCM = 6022768500/25

LCM = 240910740

Thus, we can understand that the LCM of 815,161,340,135 is 240910740.
