Given numbers are 856,893,221,866

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

The LCM of 856,893,221,866 is 73148494744.

Find LCM of 856,893,221,866 with Prime Factorization

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

2 x 428 x 893 x 221 x 433 = 73148494744

Therefore, the lowest common multiple of 856,893,221,866 is 73148494744.

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.

856 x 893 x 221 x 866 = 146296989488

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

893 : 1, 19, 47, 893

221 : 1, 13, 17, 221

866 : 1, 2, 433, 866

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,893,221,866, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

893:19x 47

221:13x 17

866:2x 433

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 = 146296989488/(1x2)

LCM = 146296989488/2

LCM = 73148494744

Thus, we can understand that the LCM of 856,893,221,866 is 73148494744.
