Given numbers are 199,645,638,686

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

The LCM of 199,645,638,686 is 28088438070.

Find LCM of 199,645,638,686 with Prime Factorization

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

2 x 199 x 645 x 319 x 343 = 28088438070

Therefore, the lowest common multiple of 199,645,638,686 is 28088438070.

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 645 x 638 x 686 = 56176876140

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

645 : 1, 3, 5, 15, 43, 129, 215, 645

638 : 1, 2, 11, 22, 29, 58, 319, 638

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 199,645,638,686, is 1.

Now, the common factors can be found like this.

199:199

645:3x 5x 43

638:2x 11x 29

686:2x 7x 7x 7

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 = 56176876140/(1x2)

LCM = 56176876140/2

LCM = 28088438070

Thus, we can understand that the LCM of 199,645,638,686 is 28088438070.
