Given numbers are 423,335,920,155

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

The LCM of 423,335,920,155 is 808285320.

Find LCM of 423,335,920,155 with Prime Factorization

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

5 x 423 x 67 x 184 x 31 = 808285320

Therefore, the lowest common multiple of 423,335,920,155 is 808285320.

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.

423 x 335 x 920 x 155 = 20207133000

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.

423 : 1, 3, 9, 47, 141, 423

335 : 1, 5, 67, 335

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

155 : 1, 5, 31, 155

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,335,920,155, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

335:5x 67

920:2x 2x 2x 5x 23

155:5x 31

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 = 20207133000/(1x25)

LCM = 20207133000/25

LCM = 808285320

Thus, we can understand that the LCM of 423,335,920,155 is 808285320.
