Given numbers are 817,539,668,454

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

The LCM of 817,539,668,454 is 66774883868.

Find LCM of 817,539,668,454 with Prime Factorization

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

2 x 817 x 539 x 334 x 227 = 66774883868

Therefore, the lowest common multiple of 817,539,668,454 is 66774883868.

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.

817 x 539 x 668 x 454 = 133549767736

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.

817 : 1, 19, 43, 817

539 : 1, 7, 11, 49, 77, 539

668 : 1, 2, 4, 167, 334, 668

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,539,668,454, is 1.

Now, the common factors can be found like this.

817:19x 43

539:7x 7x 11

668:2x 2x 167

454:2x 227

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 = 133549767736/(1x2)

LCM = 133549767736/2

LCM = 66774883868

Thus, we can understand that the LCM of 817,539,668,454 is 66774883868.
