Given numbers are 805,643,730,502

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

The LCM of 805,643,730,502 is 18968519290.

Find LCM of 805,643,730,502 with Prime Factorization

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

2 x 5 x 161 x 643 x 73 x 251 = 18968519290

Therefore, the lowest common multiple of 805,643,730,502 is 18968519290.

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.

805 x 643 x 730 x 502 = 189685192900

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.

805 : 1, 5, 7, 23, 35, 115, 161, 805

643 : 1, 643

730 : 1, 2, 5, 10, 73, 146, 365, 730

502 : 1, 2, 251, 502

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,643,730,502, is 1.

Now, the common factors can be found like this.

805:5x 7x 23

643:643

730:2x 5x 73

502:2x 251

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 189685192900/(1x10)

LCM = 189685192900/10

LCM = 18968519290

Thus, we can understand that the LCM of 805,643,730,502 is 18968519290.
