Given numbers are 866,109,671,678

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

The LCM of 866,109,671,678 is 21471708786.

Find LCM of 866,109,671,678 with Prime Factorization

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

2 x 433 x 109 x 671 x 339 = 21471708786

Therefore, the lowest common multiple of 866,109,671,678 is 21471708786.

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.

866 x 109 x 671 x 678 = 42943417572

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.

866 : 1, 2, 433, 866

109 : 1, 109

671 : 1, 11, 61, 671

678 : 1, 2, 3, 6, 113, 226, 339, 678

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,109,671,678, is 1.

Now, the common factors can be found like this.

866:2x 433

109:109

671:11x 61

678:2x 3x 113

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 = 42943417572/(1x2)

LCM = 42943417572/2

LCM = 21471708786

Thus, we can understand that the LCM of 866,109,671,678 is 21471708786.
