Given numbers are 638,397,554,547

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

The LCM of 638,397,554,547 is 38377641434.

Find LCM of 638,397,554,547 with Prime Factorization

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

2 x 319 x 397 x 277 x 547 = 38377641434

Therefore, the lowest common multiple of 638,397,554,547 is 38377641434.

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 397 x 554 x 547 = 76755282868

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

397 : 1, 397

554 : 1, 2, 277, 554

547 : 1, 547

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,397,554,547, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

397:397

554:2x 277

547:547

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

2 = 2

Therefore, the value for common factors is 2.

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 = 76755282868/(1x2)

LCM = 76755282868/2

LCM = 38377641434

Thus, we can understand that the LCM of 638,397,554,547 is 38377641434.
