Given numbers are 812,905,654,278

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

The LCM of 812,905,654,278 is 33401591580.

Find LCM of 812,905,654,278 with Prime Factorization

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

2 x 406 x 905 x 327 x 139 = 33401591580

Therefore, the lowest common multiple of 812,905,654,278 is 33401591580.

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 905 x 654 x 278 = 133606366320

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

905 : 1, 5, 181, 905

654 : 1, 2, 3, 6, 109, 218, 327, 654

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,905,654,278, is 1.

Now, the common factors can be found like this.

812:2x 2x 7x 29

905:5x 181

654:2x 3x 109

278:2x 139

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 = 133606366320/(1x4)

LCM = 133606366320/4

LCM = 33401591580

Thus, we can understand that the LCM of 812,905,654,278 is 33401591580.
