Calculate the LCM of 291,165,705

Given numbers are 291,165,705

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

The LCM of 291,165,705 is 752235.

Find LCM of 291,165,705 with Prime Factorization


3 291, 165, 705
5 97, 55, 235
97, 11, 47

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

3 x 5 x 97 x 11 x 47 = 752235

Therefore, the lowest common multiple of 291,165,705 is 752235.

LCM Formula to Find Lowest Common Multiple of 291,165,705

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.

291 x 165 x 705 = 33850575

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.

291 : 1, 3, 97, 291

165 : 1, 3, 5, 11, 15, 33, 55, 165

705 : 1, 3, 5, 15, 47, 141, 235, 705

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,165,705, is 3.

Now, the common factors can be found like this.

291:3x 97

165:3x 5x 11

705:3x 5x 47

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 33850575/(3x15)

LCM = 33850575/45

LCM = 752235

Thus, we can understand that the LCM of 291,165,705 is 752235.
