Given numbers are 221,631,206,430

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

The LCM of 221,631,206,430 is 6176284790.

Find LCM of 221,631,206,430 with Prime Factorization

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

2 x 221 x 631 x 103 x 215 = 6176284790

Therefore, the lowest common multiple of 221,631,206,430 is 6176284790.

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 631 x 206 x 430 = 12352569580

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

631 : 1, 631

206 : 1, 2, 103, 206

430 : 1, 2, 5, 10, 43, 86, 215, 430

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,631,206,430, is 1.

Now, the common factors can be found like this.

221:13x 17

631:631

206:2x 103

430:2x 5x 43

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 = 12352569580/(1x2)

LCM = 12352569580/2

LCM = 6176284790

Thus, we can understand that the LCM of 221,631,206,430 is 6176284790.
