Given numbers are 281,642,691,212

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

The LCM of 281,642,691,212 is 13213724892.

Find LCM of 281,642,691,212 with Prime Factorization

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

2 x 281 x 321 x 691 x 106 = 13213724892

Therefore, the lowest common multiple of 281,642,691,212 is 13213724892.

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.

281 x 642 x 691 x 212 = 26427449784

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.

281 : 1, 281

642 : 1, 2, 3, 6, 107, 214, 321, 642

691 : 1, 691

212 : 1, 2, 4, 53, 106, 212

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,642,691,212, is 1.

Now, the common factors can be found like this.

281:281

642:2x 3x 107

691:691

212:2x 2x 53

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

2 = 2

Therefore, the value for common factors is 2.

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 = 26427449784/(1x2)

LCM = 26427449784/2

LCM = 13213724892

Thus, we can understand that the LCM of 281,642,691,212 is 13213724892.
