Given numbers are 417,638,305,407

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

The LCM of 417,638,305,407 is 3002329110.

Find LCM of 417,638,305,407 with Prime Factorization

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

11 x 417 x 58 x 305 x 37 = 3002329110

Therefore, the lowest common multiple of 417,638,305,407 is 3002329110.

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.

417 x 638 x 305 x 407 = 33025620210

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.

417 : 1, 3, 139, 417

638 : 1, 2, 11, 22, 29, 58, 319, 638

305 : 1, 5, 61, 305

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,638,305,407, is 1.

Now, the common factors can be found like this.

417:3x 139

638:2x 11x 29

305:5x 61

407:11x 37

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

11 = 11

Therefore, the value for common factors is 11.

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 = 33025620210/(1x11)

LCM = 33025620210/11

LCM = 3002329110

Thus, we can understand that the LCM of 417,638,305,407 is 3002329110.
