Given numbers are 407,866,958,921

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

The LCM of 407,866,958,921 is 155491783458.

Find LCM of 407,866,958,921 with Prime Factorization

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

2 x 407 x 433 x 479 x 921 = 155491783458

Therefore, the lowest common multiple of 407,866,958,921 is 155491783458.

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.

407 x 866 x 958 x 921 = 310983566916

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.

407 : 1, 11, 37, 407

866 : 1, 2, 433, 866

958 : 1, 2, 479, 958

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,866,958,921, is 1.

Now, the common factors can be found like this.

407:11x 37

866:2x 433

958:2x 479

921:3x 307

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 = 310983566916/(1x2)

LCM = 310983566916/2

LCM = 155491783458

Thus, we can understand that the LCM of 407,866,958,921 is 155491783458.
