Calculate the LCM of 689,154,284,521,207

Given numbers are 689,154,284,521,207

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

The LCM of 689,154,284,521,207 is 1624936357044.

Find LCM of 689,154,284,521,207 with Prime Factorization


2 689, 154, 284, 521, 207
689, 77, 142, 521, 207

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

2 x 689 x 77 x 142 x 521 x 207 = 1624936357044

Therefore, the lowest common multiple of 689,154,284,521,207 is 1624936357044.

LCM Formula to Find Lowest Common Multiple of 689,154,284,521,207

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.

689 x 154 x 284 x 521 x 207 = 3249872714088

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.

689 : 1, 13, 53, 689

154 : 1, 2, 7, 11, 14, 22, 77, 154

284 : 1, 2, 4, 71, 142, 284

521 : 1, 521

207 : 1, 3, 9, 23, 69, 207

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,154,284,521,207, is 1.

Now, the common factors can be found like this.

689:13x 53

154:2x 7x 11

284:2x 2x 71

521:521

207:3x 3x 23

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

2 = 2

Therefore, the value for common factors is 2.

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 = 3249872714088/(1x2)

LCM = 3249872714088/2

LCM = 1624936357044

Thus, we can understand that the LCM of 689,154,284,521,207 is 1624936357044.
