Given numbers are 669,669,972

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

The LCM of 669,669,972 is 216756.

Find LCM of 669,669,972 with Prime Factorization

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

3 x 223 x 1 x 1 x 324 = 216756

Therefore, the lowest common multiple of 669,669,972 is 216756.

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 669 x 972 = 435029292

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

669 : 1, 3, 223, 669

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,669,972, is 3.

Now, the common factors can be found like this.

669:3x 223

669:3x 223

972:2x 2x 3x 3x 3x 3x 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 223 = 669

Therefore, the value for common factors is 669.

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 = 435029292/(3x669)

LCM = 435029292/2007

LCM = 216756

Thus, we can understand that the LCM of 669,669,972 is 216756.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 218, 161, 324
