Given numbers are 647,395,715,860

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

The LCM of 647,395,715,860 is 6285876740.

Find LCM of 647,395,715,860 with Prime Factorization

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

5 x 647 x 79 x 143 x 172 = 6285876740

Therefore, the lowest common multiple of 647,395,715,860 is 6285876740.

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.

647 x 395 x 715 x 860 = 157146918500

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.

647 : 1, 647

395 : 1, 5, 79, 395

715 : 1, 5, 11, 13, 55, 65, 143, 715

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,395,715,860, is 1.

Now, the common factors can be found like this.

647:647

395:5x 79

715:5x 11x 13

860:2x 2x 5x 43

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 157146918500/(1x25)

LCM = 157146918500/25

LCM = 6285876740

Thus, we can understand that the LCM of 647,395,715,860 is 6285876740.
