Given numbers are 811,618,728,197,457

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

The LCM of 811,618,728,197,457 is 16424537126088.

Find LCM of 811,618,728,197,457 with Prime Factorization

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

2 x 811 x 309 x 364 x 197 x 457 = 16424537126088

Therefore, the lowest common multiple of 811,618,728,197,457 is 16424537126088.

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.

811 x 618 x 728 x 197 x 457 = 32849074252176

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.

811 : 1, 811

618 : 1, 2, 3, 6, 103, 206, 309, 618

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

197 : 1, 197

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,618,728,197,457, is 1.

Now, the common factors can be found like this.

811:811

618:2x 3x 103

728:2x 2x 2x 7x 13

197:197

457:457

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 = 32849074252176/(1x2)

LCM = 32849074252176/2

LCM = 16424537126088

Thus, we can understand that the LCM of 811,618,728,197,457 is 16424537126088.
