Given numbers are 638,393,395,365

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

The LCM of 638,393,395,365 is 7229914890.

Find LCM of 638,393,395,365 with Prime Factorization

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

5 x 638 x 393 x 79 x 73 = 7229914890

Therefore, the lowest common multiple of 638,393,395,365 is 7229914890.

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.

638 x 393 x 395 x 365 = 36149574450

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.

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

393 : 1, 3, 131, 393

395 : 1, 5, 79, 395

365 : 1, 5, 73, 365

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,393,395,365, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

393:3x 131

395:5x 79

365:5x 73

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

5 = 5

Therefore, the value for common factors is 5.

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 = 36149574450/(1x5)

LCM = 36149574450/5

LCM = 7229914890

Thus, we can understand that the LCM of 638,393,395,365 is 7229914890.
