Given numbers are 789,403,221,221

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

The LCM of 789,403,221,221 is 5405439.

Find LCM of 789,403,221,221 with Prime Factorization

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

13 x 17 x 789 x 31 x 1 x 1 = 5405439

Therefore, the lowest common multiple of 789,403,221,221 is 5405439.

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.

789 x 403 x 221 x 221 = 15529826247

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.

789 : 1, 3, 263, 789

403 : 1, 13, 31, 403

221 : 1, 13, 17, 221

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,403,221,221, is 1.

Now, the common factors can be found like this.

789:3x 263

403:13x 31

221:13x 17

221:13x 17

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 17 = 2873

Therefore, the value for common factors is 2873.

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 = 15529826247/(1x2873)

LCM = 15529826247/2873

LCM = 5405439

Thus, we can understand that the LCM of 789,403,221,221 is 5405439.
