Given numbers are 863,394,782,990

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

The LCM of 863,394,782,990 is 65809557990.

Find LCM of 863,394,782,990 with Prime Factorization

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

2 x 863 x 197 x 391 x 495 = 65809557990

Therefore, the lowest common multiple of 863,394,782,990 is 65809557990.

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.

863 x 394 x 782 x 990 = 263238231960

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.

863 : 1, 863

394 : 1, 2, 197, 394

782 : 1, 2, 17, 23, 34, 46, 391, 782

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,394,782,990, is 1.

Now, the common factors can be found like this.

863:863

394:2x 197

782:2x 17x 23

990:2x 3x 3x 5x 11

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 = 263238231960/(1x4)

LCM = 263238231960/4

LCM = 65809557990

Thus, we can understand that the LCM of 863,394,782,990 is 65809557990.
