Given numbers are 798,216,427,447,728

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

The LCM of 798,216,427,447,728 is 3394414296.

Find LCM of 798,216,427,447,728 with Prime Factorization

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

2 x 2 x 2 x 3 x 7 x 19 x 9 x 61 x 149 x 13 = 3394414296

Therefore, the lowest common multiple of 798,216,427,447,728 is 3394414296.

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.

798 x 216 x 427 x 447 x 728 = 23950987272576

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.

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216

427 : 1, 7, 61, 427

447 : 1, 3, 149, 447

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,216,427,447,728, is 1.

Now, the common factors can be found like this.

798:2x 3x 7x 19

216:2x 2x 2x 3x 3x 3

427:7x 61

447:3x 149

728:2x 2x 2x 7x 13

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

2x 2x 2x 2x 3x 3x 7x 7 = 7056

Therefore, the value for common factors is 7056.

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 = 23950987272576/(1x7056)

LCM = 23950987272576/7056

LCM = 3394414296

Thus, we can understand that the LCM of 798,216,427,447,728 is 3394414296.
