Given numbers are 109,905,417,861

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

The LCM of 109,905,417,861 is 11805734955.

Find LCM of 109,905,417,861 with Prime Factorization

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

3 x 109 x 905 x 139 x 287 = 11805734955

Therefore, the lowest common multiple of 109,905,417,861 is 11805734955.

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.

109 x 905 x 417 x 861 = 35417204865

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.

109 : 1, 109

905 : 1, 5, 181, 905

417 : 1, 3, 139, 417

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 109,905,417,861, is 1.

Now, the common factors can be found like this.

109:109

905:5x 181

417:3x 139

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 = 35417204865/(1x3)

LCM = 35417204865/3

LCM = 11805734955

Thus, we can understand that the LCM of 109,905,417,861 is 11805734955.
