Given numbers are 865,642,857,851,861

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

The LCM of 865,642,857,851,861 is 116236738160970.

Find LCM of 865,642,857,851,861 with Prime Factorization

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

3 x 865 x 214 x 857 x 851 x 287 = 116236738160970

Therefore, the lowest common multiple of 865,642,857,851,861 is 116236738160970.

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.

865 x 642 x 857 x 851 x 861 = 348710214482910

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.

865 : 1, 5, 173, 865

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

857 : 1, 857

851 : 1, 23, 37, 851

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,642,857,851,861, is 1.

Now, the common factors can be found like this.

865:5x 173

642:2x 3x 107

857:857

851:23x 37

861:3x 7x 41

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

3 = 3

Therefore, the value for common factors is 3.

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 = 348710214482910/(1x3)

LCM = 348710214482910/3

LCM = 116236738160970

Thus, we can understand that the LCM of 865,642,857,851,861 is 116236738160970.
