Calculate the LCM of 969,221,768

Given numbers are 969,221,768

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

The LCM of 969,221,768 is 3224832.

Find LCM of 969,221,768 with Prime Factorization


3 969, 221, 768
17 323, 221, 256
19, 13, 256

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

3 x 17 x 19 x 13 x 256 = 3224832

Therefore, the lowest common multiple of 969,221,768 is 3224832.

LCM Formula to Find Lowest Common Multiple of 969,221,768

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.

969 x 221 x 768 = 164466432

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.

969 : 1, 3, 17, 19, 51, 57, 323, 969

221 : 1, 13, 17, 221

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,221,768, is 1.

Now, the common factors can be found like this.

969:3x 17x 19

221:13x 17

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.

3x 17 = 51

Therefore, the value for common factors is 51.

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 = 164466432/(1x51)

LCM = 164466432/51

LCM = 3224832

Thus, we can understand that the LCM of 969,221,768 is 3224832.
