Calculate the LCM of 309,201,315,669

Given numbers are 309,201,315,669

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

The LCM of 309,201,315,669 is 484760745.

Find LCM of 309,201,315,669 with Prime Factorization


3 309, 201, 315, 669
103, 67, 105, 223

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

3 x 103 x 67 x 105 x 223 = 484760745

Therefore, the lowest common multiple of 309,201,315,669 is 484760745.

LCM Formula to Find Lowest Common Multiple of 309,201,315,669

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.

309 x 201 x 315 x 669 = 13088540115

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.

309 : 1, 3, 103, 309

201 : 1, 3, 67, 201

315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315

669 : 1, 3, 223, 669

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,201,315,669, is 3.

Now, the common factors can be found like this.

309:3x 103

201:3x 67

315:3x 3x 5x 7

669:3x 223

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 13088540115/(3x9)

LCM = 13088540115/27

LCM = 484760745

Thus, we can understand that the LCM of 309,201,315,669 is 484760745.
