Given numbers are 177,305,320,505

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

The LCM of 177,305,320,505 is 348959040.

Find LCM of 177,305,320,505 with Prime Factorization

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

5 x 177 x 61 x 64 x 101 = 348959040

Therefore, the lowest common multiple of 177,305,320,505 is 348959040.

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.

177 x 305 x 320 x 505 = 8723976000

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.

177 : 1, 3, 59, 177

305 : 1, 5, 61, 305

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

505 : 1, 5, 101, 505

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,305,320,505, is 1.

Now, the common factors can be found like this.

177:3x 59

305:5x 61

320:2x 2x 2x 2x 2x 2x 5

505:5x 101

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 = 8723976000/(1x25)

LCM = 8723976000/25

LCM = 348959040

Thus, we can understand that the LCM of 177,305,320,505 is 348959040.
