Given numbers are 281,817,802,215

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

The LCM of 281,817,802,215 is 920603770.

Find LCM of 281,817,802,215 with Prime Factorization

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

43 x 281 x 19 x 802 x 5 = 920603770

Therefore, the lowest common multiple of 281,817,802,215 is 920603770.

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.

281 x 817 x 802 x 215 = 39585962110

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.

281 : 1, 281

817 : 1, 19, 43, 817

802 : 1, 2, 401, 802

215 : 1, 5, 43, 215

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,817,802,215, is 1.

Now, the common factors can be found like this.

281:281

817:19x 43

802:2x 401

215:5x 43

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

43 = 43

Therefore, the value for common factors is 43.

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 = 39585962110/(1x43)

LCM = 39585962110/43

LCM = 920603770

Thus, we can understand that the LCM of 281,817,802,215 is 920603770.
