Given numbers are 393,882,780,994

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

The LCM of 393,882,780,994 is 1066452660.

Find LCM of 393,882,780,994 with Prime Factorization

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

2 x 3 x 7 x 131 x 21 x 130 x 71 = 1066452660

Therefore, the lowest common multiple of 393,882,780,994 is 1066452660.

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.

393 x 882 x 780 x 994 = 268746070320

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.

393 : 1, 3, 131, 393

882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

994 : 1, 2, 7, 14, 71, 142, 497, 994

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,882,780,994, is 1.

Now, the common factors can be found like this.

393:3x 131

882:2x 3x 3x 7x 7

780:2x 2x 3x 5x 13

994:2x 7x 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 2x 3x 3x 7 = 252

Therefore, the value for common factors is 252.

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 = 268746070320/(1x252)

LCM = 268746070320/252

LCM = 1066452660

Thus, we can understand that the LCM of 393,882,780,994 is 1066452660.
