Given numbers are 808,440,164,420,988

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

The LCM of 808,440,164,420,988 is 9450921480.

Find LCM of 808,440,164,420,988 with Prime Factorization

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

2 x 2 x 2 x 5 x 101 x 11 x 41 x 21 x 247 = 9450921480

Therefore, the lowest common multiple of 808,440,164,420,988 is 9450921480.

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.

808 x 440 x 164 x 420 x 988 = 24194358988800

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.

808 : 1, 2, 4, 8, 101, 202, 404, 808

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

164 : 1, 2, 4, 41, 82, 164

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

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

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,440,164,420,988, is 4.

Now, the common factors can be found like this.

808:2x 2x 2x 101

440:2x 2x 2x 5x 11

164:2x 2x 41

420:2x 2x 3x 5x 7

988:2x 2x 13x 19

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

2x 2x 2x 2x 2x 2x 2x 5 = 640

Therefore, the value for common factors is 640.

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 = 24194358988800/(4x640)

LCM = 24194358988800/2560

LCM = 9450921480

Thus, we can understand that the LCM of 808,440,164,420,988 is 9450921480.
