Given numbers are 904,642,286,381

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

The LCM of 904,642,286,381 is 5270031624.

Find LCM of 904,642,286,381 with Prime Factorization

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

2 x 3 x 452 x 107 x 143 x 127 = 5270031624

Therefore, the lowest common multiple of 904,642,286,381 is 5270031624.

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.

904 x 642 x 286 x 381 = 63240379488

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.

904 : 1, 2, 4, 8, 113, 226, 452, 904

642 : 1, 2, 3, 6, 107, 214, 321, 642

286 : 1, 2, 11, 13, 22, 26, 143, 286

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,642,286,381, is 1.

Now, the common factors can be found like this.

904:2x 2x 2x 113

642:2x 3x 107

286:2x 11x 13

381:3x 127

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 3 = 12

Therefore, the value for common factors is 12.

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 = 63240379488/(1x12)

LCM = 63240379488/12

LCM = 5270031624

Thus, we can understand that the LCM of 904,642,286,381 is 5270031624.
