Given numbers are 561,669,339,515

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

The LCM of 561,669,339,515 is 7280369085.

Find LCM of 561,669,339,515 with Prime Factorization

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

3 x 187 x 223 x 113 x 515 = 7280369085

Therefore, the lowest common multiple of 561,669,339,515 is 7280369085.

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.

561 x 669 x 339 x 515 = 65523321765

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

669 : 1, 3, 223, 669

339 : 1, 3, 113, 339

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,669,339,515, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

669:3x 223

339:3x 113

515:5x 103

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 = 65523321765/(1x9)

LCM = 65523321765/9

LCM = 7280369085

Thus, we can understand that the LCM of 561,669,339,515 is 7280369085.
