Given numbers are 199,987,789,517

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

The LCM of 199,987,789,517 is 568222809.

Find LCM of 199,987,789,517 with Prime Factorization

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

3 x 47 x 199 x 7 x 263 x 11 = 568222809

Therefore, the lowest common multiple of 199,987,789,517 is 568222809.

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 987 x 789 x 517 = 80119416069

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

987 : 1, 3, 7, 21, 47, 141, 329, 987

789 : 1, 3, 263, 789

517 : 1, 11, 47, 517

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 199,987,789,517, is 1.

Now, the common factors can be found like this.

199:199

987:3x 7x 47

789:3x 263

517:11x 47

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 47 = 141

Therefore, the value for common factors is 141.

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 = 80119416069/(1x141)

LCM = 80119416069/141

LCM = 568222809

Thus, we can understand that the LCM of 199,987,789,517 is 568222809.
