Given numbers are 286,575,421,663

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

The LCM of 286,575,421,663 is 3530905950.

Find LCM of 286,575,421,663 with Prime Factorization

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

13 x 22 x 575 x 421 x 51 = 3530905950

Therefore, the lowest common multiple of 286,575,421,663 is 3530905950.

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.

286 x 575 x 421 x 663 = 45901777350

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.

286 : 1, 2, 11, 13, 22, 26, 143, 286

575 : 1, 5, 23, 25, 115, 575

421 : 1, 421

663 : 1, 3, 13, 17, 39, 51, 221, 663

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,575,421,663, is 1.

Now, the common factors can be found like this.

286:2x 11x 13

575:5x 5x 23

421:421

663:3x 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 = 45901777350/(1x13)

LCM = 45901777350/13

LCM = 3530905950

Thus, we can understand that the LCM of 286,575,421,663 is 3530905950.
