Given numbers are 407,991,349,522,861

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

The LCM of 407,991,349,522,861 is 21088509731982.

Find LCM of 407,991,349,522,861 with Prime Factorization

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

3 x 407 x 991 x 349 x 174 x 287 = 21088509731982

Therefore, the lowest common multiple of 407,991,349,522,861 is 21088509731982.

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 991 x 349 x 522 x 861 = 63265529195946

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

991 : 1, 991

349 : 1, 349

522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522

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 407,991,349,522,861, is 1.

Now, the common factors can be found like this.

407:11x 37

991:991

349:349

522:2x 3x 3x 29

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 = 63265529195946/(1x3)

LCM = 63265529195946/3

LCM = 21088509731982

Thus, we can understand that the LCM of 407,991,349,522,861 is 21088509731982.
