Given numbers are 199,988,639,868

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

The LCM of 199,988,639,868 is 27262809756.

Find LCM of 199,988,639,868 with Prime Factorization

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

2 x 2 x 199 x 247 x 639 x 217 = 27262809756

Therefore, the lowest common multiple of 199,988,639,868 is 27262809756.

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 988 x 639 x 868 = 109051239024

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

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

639 : 1, 3, 9, 71, 213, 639

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 199,988,639,868, is 1.

Now, the common factors can be found like this.

199:199

988:2x 2x 13x 19

639:3x 3x 71

868:2x 2x 7x 31

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 = 109051239024/(1x4)

LCM = 109051239024/4

LCM = 27262809756

Thus, we can understand that the LCM of 199,988,639,868 is 27262809756.
