Calculate the LCM of 288,556,561,669

Given numbers are 288,556,561,669

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

The LCM of 288,556,561,669 is 1669374432.

Find LCM of 288,556,561,669 with Prime Factorization


2 288, 556, 561, 669
2 144, 278, 561, 669
3 72, 139, 561, 669
24, 139, 187, 223

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

2 x 2 x 3 x 24 x 139 x 187 x 223 = 1669374432

Therefore, the lowest common multiple of 288,556,561,669 is 1669374432.

LCM Formula to Find Lowest Common Multiple of 288,556,561,669

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.

288 x 556 x 561 x 669 = 60097479552

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.

288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288

556 : 1, 2, 4, 139, 278, 556

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

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 288,556,561,669, is 1.

Now, the common factors can be found like this.

288:2x 2x 2x 2x 2x 3x 3

556:2x 2x 139

561:3x 11x 17

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.

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 60097479552/(1x36)

LCM = 60097479552/36

LCM = 1669374432

Thus, we can understand that the LCM of 288,556,561,669 is 1669374432.
