Given numbers are 284,386,746,991

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

The LCM of 284,386,746,991 is 20260872116.

Find LCM of 284,386,746,991 with Prime Factorization

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

2 x 142 x 193 x 373 x 991 = 20260872116

Therefore, the lowest common multiple of 284,386,746,991 is 20260872116.

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.

284 x 386 x 746 x 991 = 81043488464

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.

284 : 1, 2, 4, 71, 142, 284

386 : 1, 2, 193, 386

746 : 1, 2, 373, 746

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 284,386,746,991, is 1.

Now, the common factors can be found like this.

284:2x 2x 71

386:2x 193

746:2x 373

991:991

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 = 81043488464/(1x4)

LCM = 81043488464/4

LCM = 20260872116

Thus, we can understand that the LCM of 284,386,746,991 is 20260872116.
