Given numbers are 286,221,788,993

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

The LCM of 286,221,788,993 is 1902218604.

Find LCM of 286,221,788,993 with Prime Factorization

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

2 x 13 x 11 x 17 x 394 x 993 = 1902218604

Therefore, the lowest common multiple of 286,221,788,993 is 1902218604.

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.

286 x 221 x 788 x 993 = 49457683704

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.

286 : 1, 2, 11, 13, 22, 26, 143, 286

221 : 1, 13, 17, 221

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

993 : 1, 3, 331, 993

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,221,788,993, is 1.

Now, the common factors can be found like this.

286:2x 11x 13

221:13x 17

788:2x 2x 197

993:3x 331

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 49457683704/(1x26)

LCM = 49457683704/26

LCM = 1902218604

Thus, we can understand that the LCM of 286,221,788,993 is 1902218604.
