Given numbers are 638,514,358,133

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

The LCM of 638,514,358,133 is 3903538562.

Find LCM of 638,514,358,133 with Prime Factorization

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

2 x 319 x 257 x 179 x 133 = 3903538562

Therefore, the lowest common multiple of 638,514,358,133 is 3903538562.

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 514 x 358 x 133 = 15614154248

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

514 : 1, 2, 257, 514

358 : 1, 2, 179, 358

133 : 1, 7, 19, 133

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,514,358,133, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

514:2x 257

358:2x 179

133:7x 19

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 = 15614154248/(1x4)

LCM = 15614154248/4

LCM = 3903538562

Thus, we can understand that the LCM of 638,514,358,133 is 3903538562.
