Given numbers are 221,394,420,803

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

The LCM of 221,394,420,803 is 14683288620.

Find LCM of 221,394,420,803 with Prime Factorization

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

2 x 221 x 197 x 210 x 803 = 14683288620

Therefore, the lowest common multiple of 221,394,420,803 is 14683288620.

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.

221 x 394 x 420 x 803 = 29366577240

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.

221 : 1, 13, 17, 221

394 : 1, 2, 197, 394

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

803 : 1, 11, 73, 803

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,394,420,803, is 1.

Now, the common factors can be found like this.

221:13x 17

394:2x 197

420:2x 2x 3x 5x 7

803:11x 73

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

2 = 2

Therefore, the value for common factors is 2.

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 = 29366577240/(1x2)

LCM = 29366577240/2

LCM = 14683288620

Thus, we can understand that the LCM of 221,394,420,803 is 14683288620.
