Given numbers are 656,743,676,687

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

The LCM of 656,743,676,687 is 56589531024.

Find LCM of 656,743,676,687 with Prime Factorization

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

2 x 2 x 164 x 743 x 169 x 687 = 56589531024

Therefore, the lowest common multiple of 656,743,676,687 is 56589531024.

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.

656 x 743 x 676 x 687 = 226358124096

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.

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

743 : 1, 743

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 656,743,676,687, is 1.

Now, the common factors can be found like this.

656:2x 2x 2x 2x 41

743:743

676:2x 2x 13x 13

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 226358124096/(1x4)

LCM = 226358124096/4

LCM = 56589531024

Thus, we can understand that the LCM of 656,743,676,687 is 56589531024.
