Given numbers are 946,396,990,788

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

The LCM of 946,396,990,788 is 16772580.

Find LCM of 946,396,990,788 with Prime Factorization

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

2 x 2 x 3 x 3 x 11 x 43 x 1 x 5 x 197 = 16772580

Therefore, the lowest common multiple of 946,396,990,788 is 16772580.

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.

946 x 396 x 990 x 788 = 292245433920

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.

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

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

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

788 : 1, 2, 4, 197, 394, 788

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,396,990,788, is 2.

Now, the common factors can be found like this.

946:2x 11x 43

396:2x 2x 3x 3x 11

990:2x 3x 3x 5x 11

788:2x 2x 197

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

2x 2x 2x 3x 3x 11x 11 = 8712

Therefore, the value for common factors is 8712.

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 = 292245433920/(2x8712)

LCM = 292245433920/17424

LCM = 16772580

Thus, we can understand that the LCM of 946,396,990,788 is 16772580.
