Given numbers are 391,605,570,865

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

The LCM of 391,605,570,865 is 4665337710.

Find LCM of 391,605,570,865 with Prime Factorization

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

5 x 391 x 121 x 114 x 173 = 4665337710

Therefore, the lowest common multiple of 391,605,570,865 is 4665337710.

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.

391 x 605 x 570 x 865 = 116633442750

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.

391 : 1, 17, 23, 391

605 : 1, 5, 11, 55, 121, 605

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,605,570,865, is 1.

Now, the common factors can be found like this.

391:17x 23

605:5x 11x 11

570:2x 3x 5x 19

865:5x 173

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 = 116633442750/(1x25)

LCM = 116633442750/25

LCM = 4665337710

Thus, we can understand that the LCM of 391,605,570,865 is 4665337710.
