Given numbers are 199,668,436,721

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

The LCM of 199,668,436,721 is 10446992948.

Find LCM of 199,668,436,721 with Prime Factorization

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

2 x 2 x 199 x 167 x 109 x 721 = 10446992948

Therefore, the lowest common multiple of 199,668,436,721 is 10446992948.

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.

199 x 668 x 436 x 721 = 41787971792

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.

199 : 1, 199

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

436 : 1, 2, 4, 109, 218, 436

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 199,668,436,721, is 1.

Now, the common factors can be found like this.

199:199

668:2x 2x 167

436:2x 2x 109

721:7x 103

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 = 41787971792/(1x4)

LCM = 41787971792/4

LCM = 10446992948

Thus, we can understand that the LCM of 199,668,436,721 is 10446992948.
