Given numbers are 659,865,882,21

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

The LCM of 659,865,882,21 is 502770870.

Find LCM of 659,865,882,21 with Prime Factorization

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

3 x 7 x 659 x 865 x 42 x 1 = 502770870

Therefore, the lowest common multiple of 659,865,882,21 is 502770870.

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.

659 x 865 x 882 x 21 = 10558188270

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.

659 : 1, 659

865 : 1, 5, 173, 865

882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882

21 : 1, 3, 7, 21

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 659,865,882,21, is 1.

Now, the common factors can be found like this.

659:659

865:5x 173

882:2x 3x 3x 7x 7

21:3x 7

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 10558188270/(1x21)

LCM = 10558188270/21

LCM = 502770870

Thus, we can understand that the LCM of 659,865,882,21 is 502770870.
