Given numbers are 817,641,286,282

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

The LCM of 817,641,286,282 is 21118605222.

Find LCM of 817,641,286,282 with Prime Factorization

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

2 x 817 x 641 x 143 x 141 = 21118605222

Therefore, the lowest common multiple of 817,641,286,282 is 21118605222.

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.

817 x 641 x 286 x 282 = 42237210444

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.

817 : 1, 19, 43, 817

641 : 1, 641

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

282 : 1, 2, 3, 6, 47, 94, 141, 282

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,641,286,282, is 1.

Now, the common factors can be found like this.

817:19x 43

641:641

286:2x 11x 13

282:2x 3x 47

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

2 = 2

Therefore, the value for common factors is 2.

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 = 42237210444/(1x2)

LCM = 42237210444/2

LCM = 21118605222

Thus, we can understand that the LCM of 817,641,286,282 is 21118605222.
