Given numbers are 812,438,163,828

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

The LCM of 812,438,163,828 is 2000031516.

Find LCM of 812,438,163,828 with Prime Factorization

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

2 x 2 x 3 x 203 x 73 x 163 x 69 = 2000031516

Therefore, the lowest common multiple of 812,438,163,828 is 2000031516.

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.

812 x 438 x 163 x 828 = 48000756384

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.

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

438 : 1, 2, 3, 6, 73, 146, 219, 438

163 : 1, 163

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,438,163,828, is 1.

Now, the common factors can be found like this.

812:2x 2x 7x 29

438:2x 3x 73

163:163

828:2x 2x 3x 3x 23

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 3 = 24

Therefore, the value for common factors is 24.

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 = 48000756384/(1x24)

LCM = 48000756384/24

LCM = 2000031516

Thus, we can understand that the LCM of 812,438,163,828 is 2000031516.
