Given numbers are 534,921,905,861

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

The LCM of 534,921,905,861 is 42580436430.

Find LCM of 534,921,905,861 with Prime Factorization

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

3 x 178 x 307 x 905 x 287 = 42580436430

Therefore, the lowest common multiple of 534,921,905,861 is 42580436430.

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.

534 x 921 x 905 x 861 = 383223927870

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.

534 : 1, 2, 3, 6, 89, 178, 267, 534

921 : 1, 3, 307, 921

905 : 1, 5, 181, 905

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 534,921,905,861, is 1.

Now, the common factors can be found like this.

534:2x 3x 89

921:3x 307

905:5x 181

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.

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 383223927870/(1x9)

LCM = 383223927870/9

LCM = 42580436430

Thus, we can understand that the LCM of 534,921,905,861 is 42580436430.
