Given numbers are 867,721,436,721

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

The LCM of 867,721,436,721 is 272546652.

Find LCM of 867,721,436,721 with Prime Factorization

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

7 x 103 x 867 x 1 x 436 x 1 = 272546652

Therefore, the lowest common multiple of 867,721,436,721 is 272546652.

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.

867 x 721 x 436 x 721 = 196506136092

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.

867 : 1, 3, 17, 51, 289, 867

721 : 1, 7, 103, 721

436 : 1, 2, 4, 109, 218, 436

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,721,436,721, is 1.

Now, the common factors can be found like this.

867:3x 17x 17

721:7x 103

436:2x 2x 109

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.

7x 103 = 721

Therefore, the value for common factors is 721.

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 = 196506136092/(1x721)

LCM = 196506136092/721

LCM = 272546652

Thus, we can understand that the LCM of 867,721,436,721 is 272546652.
