Given numbers are 445,987,394,782,221

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

The LCM of 445,987,394,782,221 is 879616758930.

Find LCM of 445,987,394,782,221 with Prime Factorization

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

2 x 17 x 445 x 987 x 197 x 23 x 13 = 879616758930

Therefore, the lowest common multiple of 445,987,394,782,221 is 879616758930.

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.

445 x 987 x 394 x 782 x 221 = 29906969803620

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.

445 : 1, 5, 89, 445

987 : 1, 3, 7, 21, 47, 141, 329, 987

394 : 1, 2, 197, 394

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

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,987,394,782,221, is 1.

Now, the common factors can be found like this.

445:5x 89

987:3x 7x 47

394:2x 197

782:2x 17x 23

221:13x 17

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 29906969803620/(1x34)

LCM = 29906969803620/34

LCM = 879616758930

Thus, we can understand that the LCM of 445,987,394,782,221 is 879616758930.
