Given numbers are 681,455,884

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

The LCM of 681,455,884 is 21070140.

Find LCM of 681,455,884 with Prime Factorization

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

13 x 681 x 35 x 68 = 21070140

Therefore, the lowest common multiple of 681,455,884 is 21070140.

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.

681 x 455 x 884 = 273911820

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.

681 : 1, 3, 227, 681

455 : 1, 5, 7, 13, 35, 65, 91, 455

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,455,884, is 1.

Now, the common factors can be found like this.

681:3x 227

455:5x 7x 13

884:2x 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 = 273911820/(1x13)

LCM = 273911820/13

LCM = 21070140

Thus, we can understand that the LCM of 681,455,884 is 21070140.
