Given numbers are 447,805,257,128,830

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

The LCM of 447,805,257,128,830 is 982481969280.

Find LCM of 447,805,257,128,830 with Prime Factorization

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

2 x 5 x 447 x 161 x 257 x 64 x 83 = 982481969280

Therefore, the lowest common multiple of 447,805,257,128,830 is 982481969280.

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.

447 x 805 x 257 x 128 x 830 = 9824819692800

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.

447 : 1, 3, 149, 447

805 : 1, 5, 7, 23, 35, 115, 161, 805

257 : 1, 257

128 : 1, 2, 4, 8, 16, 32, 64, 128

830 : 1, 2, 5, 10, 83, 166, 415, 830

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,805,257,128,830, is 1.

Now, the common factors can be found like this.

447:3x 149

805:5x 7x 23

257:257

128:2x 2x 2x 2x 2x 2x 2

830:2x 5x 83

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 9824819692800/(1x10)

LCM = 9824819692800/10

LCM = 982481969280

Thus, we can understand that the LCM of 447,805,257,128,830 is 982481969280.
