Given numbers are 112,891,386,721

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

The LCM of 112,891,386,721 is 1983765168.

Find LCM of 112,891,386,721 with Prime Factorization

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

2 x 7 x 8 x 891 x 193 x 103 = 1983765168

Therefore, the lowest common multiple of 112,891,386,721 is 1983765168.

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.

112 x 891 x 386 x 721 = 27772712352

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.

112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

386 : 1, 2, 193, 386

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 112,891,386,721, is 1.

Now, the common factors can be found like this.

112:2x 2x 2x 2x 7

891:3x 3x 3x 3x 11

386:2x 193

721:7x 103

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 27772712352/(1x14)

LCM = 27772712352/14

LCM = 1983765168

Thus, we can understand that the LCM of 112,891,386,721 is 1983765168.
