Given numbers are 7,291,261,643

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

The LCM of 7,291,261,643 is 113951817.

Find LCM of 7,291,261,643 with Prime Factorization

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

3 x 7 x 97 x 87 x 643 = 113951817

Therefore, the lowest common multiple of 7,291,261,643 is 113951817.

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.

7 x 291 x 261 x 643 = 341855451

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.

7 : 1, 7

291 : 1, 3, 97, 291

261 : 1, 3, 9, 29, 87, 261

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,291,261,643, is 1.

Now, the common factors can be found like this.

7:7

291:3x 97

261:3x 3x 29

643:643

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

3 = 3

Therefore, the value for common factors is 3.

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 = 341855451/(1x3)

LCM = 341855451/3

LCM = 113951817

Thus, we can understand that the LCM of 7,291,261,643 is 113951817.
