Given numbers are 820,923,163,428

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

The LCM of 820,923,163,428 is 13200395260.

Find LCM of 820,923,163,428 with Prime Factorization

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

2 x 2 x 205 x 923 x 163 x 107 = 13200395260

Therefore, the lowest common multiple of 820,923,163,428 is 13200395260.

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.

820 x 923 x 163 x 428 = 52801581040

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.

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

923 : 1, 13, 71, 923

163 : 1, 163

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,923,163,428, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

923:13x 71

163:163

428:2x 2x 107

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 = 52801581040/(1x4)

LCM = 52801581040/4

LCM = 13200395260

Thus, we can understand that the LCM of 820,923,163,428 is 13200395260.
