Given numbers are 651,669,813,815,687

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

The LCM of 651,669,813,815,687 is 7342572333705.

Find LCM of 651,669,813,815,687 with Prime Factorization

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

3 x 217 x 223 x 271 x 815 x 229 = 7342572333705

Therefore, the lowest common multiple of 651,669,813,815,687 is 7342572333705.

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.

651 x 669 x 813 x 815 x 687 = 198249453010035

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.

651 : 1, 3, 7, 21, 31, 93, 217, 651

669 : 1, 3, 223, 669

813 : 1, 3, 271, 813

815 : 1, 5, 163, 815

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,669,813,815,687, is 1.

Now, the common factors can be found like this.

651:3x 7x 31

669:3x 223

813:3x 271

815:5x 163

687:3x 229

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 198249453010035/(1x27)

LCM = 198249453010035/27

LCM = 7342572333705

Thus, we can understand that the LCM of 651,669,813,815,687 is 7342572333705.
