Given numbers are 287,709,585,442

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

The LCM of 287,709,585,442 is 4047276870.

Find LCM of 287,709,585,442 with Prime Factorization

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

13 x 287 x 709 x 45 x 34 = 4047276870

Therefore, the lowest common multiple of 287,709,585,442 is 4047276870.

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.

287 x 709 x 585 x 442 = 52614599310

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.

287 : 1, 7, 41, 287

709 : 1, 709

585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,709,585,442, is 1.

Now, the common factors can be found like this.

287:7x 41

709:709

585:3x 3x 5x 13

442:2x 13x 17

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

13 = 13

Therefore, the value for common factors is 13.

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 = 52614599310/(1x13)

LCM = 52614599310/13

LCM = 4047276870

Thus, we can understand that the LCM of 287,709,585,442 is 4047276870.
