Given numbers are 721,892,818,890

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

The LCM of 721,892,818,890 is 117053239660.

Find LCM of 721,892,818,890 with Prime Factorization

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

2 x 721 x 446 x 409 x 445 = 117053239660

Therefore, the lowest common multiple of 721,892,818,890 is 117053239660.

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.

721 x 892 x 818 x 890 = 468212958640

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.

721 : 1, 7, 103, 721

892 : 1, 2, 4, 223, 446, 892

818 : 1, 2, 409, 818

890 : 1, 2, 5, 10, 89, 178, 445, 890

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,892,818,890, is 1.

Now, the common factors can be found like this.

721:7x 103

892:2x 2x 223

818:2x 409

890:2x 5x 89

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 = 468212958640/(1x4)

LCM = 468212958640/4

LCM = 117053239660

Thus, we can understand that the LCM of 721,892,818,890 is 117053239660.
