Given numbers are 809,946,639,284

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

The LCM of 809,946,639,284 is 978071292.

Find LCM of 809,946,639,284 with Prime Factorization

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

2 x 71 x 809 x 473 x 9 x 2 = 978071292

Therefore, the lowest common multiple of 809,946,639,284 is 978071292.

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.

809 x 946 x 639 x 284 = 138886123464

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.

809 : 1, 809

946 : 1, 2, 11, 22, 43, 86, 473, 946

639 : 1, 3, 9, 71, 213, 639

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,946,639,284, is 1.

Now, the common factors can be found like this.

809:809

946:2x 11x 43

639:3x 3x 71

284:2x 2x 71

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

2x 71 = 142

Therefore, the value for common factors is 142.

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 = 138886123464/(1x142)

LCM = 138886123464/142

LCM = 978071292

Thus, we can understand that the LCM of 809,946,639,284 is 978071292.
