Given numbers are 221,923,426,169

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

The LCM of 221,923,426,169 is 1223898.

Find LCM of 221,923,426,169 with Prime Factorization

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

13 x 71 x 17 x 1 x 6 x 13 = 1223898

Therefore, the lowest common multiple of 221,923,426,169 is 1223898.

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 923 x 426 x 169 = 14685552102

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

923 : 1, 13, 71, 923

426 : 1, 2, 3, 6, 71, 142, 213, 426

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,923,426,169, is 1.

Now, the common factors can be found like this.

221:13x 17

923:13x 71

426:2x 3x 71

169:13x 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 13x 71 = 11999

Therefore, the value for common factors is 11999.

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 = 14685552102/(1x11999)

LCM = 14685552102/11999

LCM = 1223898

Thus, we can understand that the LCM of 221,923,426,169 is 1223898.
