Given numbers are 668,206,669,430

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

The LCM of 668,206,669,430 is 9896423340.

Find LCM of 668,206,669,430 with Prime Factorization

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

2 x 334 x 103 x 669 x 215 = 9896423340

Therefore, the lowest common multiple of 668,206,669,430 is 9896423340.

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.

668 x 206 x 669 x 430 = 39585693360

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.

668 : 1, 2, 4, 167, 334, 668

206 : 1, 2, 103, 206

669 : 1, 3, 223, 669

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 668,206,669,430, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

206:2x 103

669:3x 223

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 39585693360/(1x4)

LCM = 39585693360/4

LCM = 9896423340

Thus, we can understand that the LCM of 668,206,669,430 is 9896423340.
