Calculate the LCM of 669,705,768

Given numbers are 669,705,768

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

The LCM of 669,705,768 is 40247040.

Find LCM of 669,705,768 with Prime Factorization


3 669, 705, 768
223, 235, 256

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

3 x 223 x 235 x 256 = 40247040

Therefore, the lowest common multiple of 669,705,768 is 40247040.

LCM Formula to Find Lowest Common Multiple of 669,705,768

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.

669 x 705 x 768 = 362223360

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.

669 : 1, 3, 223, 669

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

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,705,768, is 3.

Now, the common factors can be found like this.

669:3x 223

705:3x 5x 47

768:2x 2x 2x 2x 2x 2x 2x 2x 3

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 = 362223360/(3x3)

LCM = 362223360/9

LCM = 40247040

Thus, we can understand that the LCM of 669,705,768 is 40247040.
