Given numbers are 665,424,644,471,805

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

The LCM of 665,424,644,471,805 is 3054472680.

Find LCM of 665,424,644,471,805 with Prime Factorization

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

2 x 2 x 5 x 7 x 23 x 19 x 106 x 1 x 471 x 1 = 3054472680

Therefore, the lowest common multiple of 665,424,644,471,805 is 3054472680.

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.

665 x 424 x 644 x 471 x 805 = 68847814207200

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

424 : 1, 2, 4, 8, 53, 106, 212, 424

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

471 : 1, 3, 157, 471

805 : 1, 5, 7, 23, 35, 115, 161, 805

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,424,644,471,805, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

424:2x 2x 2x 53

644:2x 2x 7x 23

471:3x 157

805:5x 7x 23

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 5x 7x 7x 23 = 22540

Therefore, the value for common factors is 22540.

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 = 68847814207200/(1x22540)

LCM = 68847814207200/22540

LCM = 3054472680

Thus, we can understand that the LCM of 665,424,644,471,805 is 3054472680.
