The LCM of 405,170,153,587 is 8082990.

Find LCM of 405,170,153,587 with Prime Factorization


3 405, 170, 153, 587
3 135, 170, 51, 587
5 45, 170, 17, 587
17 9, 34, 17, 587
9, 2, 1, 587

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

3 x 3 x 5 x 17 x 9 x 2 x 1 x 587 = 8082990

Therefore, the lowest common multiple of 405,170,153,587 is 8082990.

LCM Formula to Find Lowest Common Multiple of 405,170,153,587

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.

405 x 170 x 153 x 587 = 6183487350

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.

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

170 : 1, 2, 5, 10, 17, 34, 85, 170

153 : 1, 3, 9, 17, 51, 153

587 : 1, 587

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,170,153,587, is 1.

Now, the common factors can be found like this.

405:3x 3x 3x 3x 5

170:2x 5x 17

153:3x 3x 17

587:587

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

3x 3x 5x 17 = 765

Therefore, the value for common factors is 765.

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 = 6183487350/(1x765)

LCM = 6183487350/765

LCM = 8082990

Thus, we can understand that the LCM of 405,170,153,587 is 8082990.
