Given numbers are 409,644,478,998

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

The LCM of 409,644,478,998 is 31412870356.

Find LCM of 409,644,478,998 with Prime Factorization

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

2 x 409 x 322 x 239 x 499 = 31412870356

Therefore, the lowest common multiple of 409,644,478,998 is 31412870356.

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.

409 x 644 x 478 x 998 = 125651481424

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.

409 : 1, 409

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

478 : 1, 2, 239, 478

998 : 1, 2, 499, 998

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,644,478,998, is 1.

Now, the common factors can be found like this.

409:409

644:2x 2x 7x 23

478:2x 239

998:2x 499

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 125651481424/(1x4)

LCM = 125651481424/4

LCM = 31412870356

Thus, we can understand that the LCM of 409,644,478,998 is 31412870356.
