Given numbers are 221,913,445,747,728

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

The LCM of 221,913,445,747,728 is 45253648440.

Find LCM of 221,913,445,747,728 with Prime Factorization

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

13 x 83 x 17 x 11 x 445 x 9 x 56 = 45253648440

Therefore, the lowest common multiple of 221,913,445,747,728 is 45253648440.

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 913 x 445 x 747 x 728 = 48828686666760

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

913 : 1, 11, 83, 913

445 : 1, 5, 89, 445

747 : 1, 3, 9, 83, 249, 747

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 221,913,445,747,728, is 1.

Now, the common factors can be found like this.

221:13x 17

913:11x 83

445:5x 89

747:3x 3x 83

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.

13x 83 = 1079

Therefore, the value for common factors is 1079.

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 = 48828686666760/(1x1079)

LCM = 48828686666760/1079

LCM = 45253648440

Thus, we can understand that the LCM of 221,913,445,747,728 is 45253648440.
